Why not prove me wrong and make a contribution relevant to the

Put your money where your (big) mouth is and explain to all why a
super-regenerative receiver will not resolve CW or SSB, when the
oscilation, although quenched, is effectively amplitude modulated
by the quenching?


Brian?

Hullo?

Are you there?

Here is your big chance to prove your superiority of knowledge about
the super-regrenerative method, but you've gone strangely silent, which
is a bit bizarre when you consider how many times you have oft

Maybe I don't understand the issue. Isn't that a valid example of a
negative frequency? There are some DSP experts in comp.dsp who talk about
negative frequency often.

If you, or, indeed, anyone else has any difficulties with the subject matter
and DSP in general, then do ask me, because having worked through
what appeared as a number of anomalies (all resolved 9 years ago
when I was working as a DSP manufacturer, picoChip in Bath, UK)
I feel sure that I'm well positioned to understand the difficulties that
others might encounter in this area.

WARNING! Make sure to search the archives and read all about his "Big K"
theory before taking seriously anything Gareth says about DSP. It'll
quickly become apparent that he has no understanding whatsoever of the
subject and you'll save yourself from wasting any time talking to him about
it.

Interestingly, the true experts of comp.dsp refer to Gareth Alun Evans
G4SDW as "that idiot from uk.radio.amateur".


LOL! I see this is cross posted to comp.dsp. I don't feel like
researching the "Big K" theory, but I would be interested in hearing a
bit if anyone cares to share the humor.


It all sprang from Gareth being corrected over one of his routine total
misunderstandings and he went off the deep end about it, as per, and cooked
up "Big K", a Time Cube like confabulation and misrepresentation of known
physics. Some time later, after receiving much mocking, he declared that
he'd found some obscure textbook (AIUI, nobody has been able to verify the
contents of this supposed textbook, or even its existence) that proved that
he was correct and that every other person on the planet was wrong and
always had been. Thereafter, he refused to be drawn further on "Big K",
saying that he had settled the matter "to [his] satisfaction".



To clarify:


His 'problem' was that he insisted that the use of the Dirac Delta
(which is 'infinite in amplitude and infinitely narrow') needed to be
compensated for by 1/K , his Big K. According to his theory, K need to
by 'Big' to compensate for the amplitude of the Dirac Delta.

Eventually, he claimed that he hadn't noticed (in the mystery book) the
1/T term (which appears in the standard formula) served the same
purpose, and thus his theory was correct and all he had done was to have
'missed' the 1/T term. This was 'dubious' for the simple reason he had
missed it for years alone. It would be in ANY book on the topic.
However, it was technically flawed, as he thought the T referred the
width of the sampling pulse. Not only wasn't that 'large' (or Big as in
his Big K) but it doesn't refer to the width of the pulse, it is the
spacing or of the pulses. This was explained at the time, it is all in
the archive, as is his abusive responses

He did vary his 'problem' from time to time (as he usually does) but the
above was the general theme.

As you say, he insisted everyone was wrong and simply 'followed the text
books' without understanding them.

Even today he denied the mention of angle yet posted a post with a
cosine identity in it. Whether he doesn't know math(s) to even that
level or it was a blatant attempt to misrepresent the facts, I leave for
others to decide. Hint: In the UK, even a KS3 pupil (about 13) knows
that sines, cosines, etc. refer to angles.

This is just one of his many bogus theories. Of course, everyone has to
learn but the thing with him is that he spends his time being abusive to
newcomers etc. when it is clear that his own technical abilities are, at
best, somewhat limited. Plus, of course, his habit of being abusive is
hardly conducive to people treating him as someone who is deserving of
help and assistance. Especially, when he starts taking his abuse to
extremes.

He seems to fill his days by trying to stir up rows and upset people. He
hasn't realised he has the 'village idiot', a malicious one, but still
the village idiot who people laugh at. He has a fan club of similar
village idiots who seem to have similar backgrounds (unhappy careers
etc.) and it is quite amusing to watch their antics and mutual back
slapping at times. They remind me of the 'bad guy' in the Cartoon series
called 'Whacky Races', whose plans always went wrong. The only
difference is, there is a pack of 'Multy the Dogs'.

Anyway, I'm going to see if I can work a few more stations then turn in.
Busy day tomorrow.

I think that there is a semantics issue here.

MP3 is lossy, it cannot be used to reproduce the original but it does
not 'remove' signal, they get lost.

IIRC some sound encoding deliberately removes some frequencies if the
are low amplitude and are close to a higher amplitude frequency.

Loses is passive, the data just gets lost. Remove implies some active
removal of data.

I am unsure of US TV. In the UK terrestrial TV is all digital.
Analog(ue) was switched off a few years ago.
I am referring to the whole box from antenna to screen, most of our TVs
come with built-in 'Freeview'.

I have a digital set about 6 years old that struggles to handle complex
images but my new toy handles it perfectly. My newer TV uses a newer
chipset and more efficient decoding algorithm that is made possible
because of the higher power chipset.

The older chipsets are still in production and still being sold,
presumably the TV manufacturers can buy them cheaply, stick them in the
TV and rely on marketing buzz over technical demonstration to sell then
for a larger markup. Most people I know buy on screen size anyway.

My understanding - which may be incorrect - is that the TV has a fixed
time based upon the framerate in which to decode the image and display
it before it has to start on the next frame.
Better quality TVs are capable of fully decompressing the image and
displaying it between frames but the cheaper and older ones cannot
handle a new image every frame and so, when it runs out of time decoding
the image it just gets sent to the screen, tesselations and all.
Standing ready to be corrected.

Andy,

You are really trying to split hairs here. The data are lost because
they are "removed" during compression. It is an active decision as to
what is compressed and what is ignored.

And yes, the term "removed" is used when describing the technical
aspects of MP3 compression.

Andy,

I don't know what the Europeans use, so I can't speak for you guys. But
here in the United States, everything is digital also, and has been for
years (here come the trolls).

Yes, the TV only has a certain amount of time to decode the signal. But
in the U.S., the method used is proprietary to one company. The
chipsets required to decode the signal are all produced by this company,
so all TV's have similar decoding.

There is a limit to how much information can be transferred in the
allotted bandwidth, so a complete change in picture can't be compressed
perfectly. But at the 30 fps used here, even a scene change is picked
up within a few frames and isn't noticeable to the eye unless you know
what you're looking for.

However, what happens after the decoding can cause more problems. The
lower quality resolutions such as 720p and 1080i typically use less
expensive circuitry when taking the decoded signal and processing it for
the display. They may or may not have the speed required to change all
of the elements in the display before the next image comes along.

Higher resolution displays such as 1080p and UHD (4K) have more
expensive circuitry to prepare the signal for the display. This
circuitry is better able to keep up with the decoded signal and a
complete scenery change is less noticeable. You may see the difference
when you have a 720p resolution set and a 1080p resolution set running
in 720p mode sitting next to each other and displaying the same information.

Of course, this is a generalization, and each set needs to be evaluated
on its own. Some lower resolution sets do quite well, while
occasionally you'll find a higher resolution set which doesn't do so
well. But it's not very common any more.

Yeah, well, that isn't so good. But it is interesting that so many

happy to pile on and give the guy grief.

The reason that it isn't so good is that it is untrue.

Huh? Are you still here? I thought you would have gone home long
ago...


Pot - kettle - black.


I've got my very own personal troll... lol


ROFLMAO! So now I'm a troll for pointing out the truth!

Why don't you discuss technical issues? Is it because I've proven you
wrong so many times? Like with mp3 compression and white noise in this
thread?

Thanks very much. Kind of you to offer. Mine's a nice bitter, maybe a

Good call! Deuchars IPA is also very popular "apud Custodum".

You are similarly obsessed and have escaped to the Canary Islands.

If you think it to be actionable then you are an even bigger fool than you
make out to be, for you have repeated the comment in public.

No problem, Mike. That file they're building on him must be massive by now!
Evans has been flailing around and lashing out at all and sundry for the
last few days, he's probably suffered another self-inflicted calamity in
his personal life.

How's life in the sun treating you this week? Dreadful weather in Kent
today, ****ing it down non-stop. Have a piña collada for me!

It remains that 100% of your postings consist of rather silly and infantile
personal remarks.

As amateur radio is a technical pursuit, and you yourself elected to
cross post to comp.dsp which is even more technical, why not make
your first technical post ever, since you first arrived to pollute Usenet
just over 2 years ago with your tirades of abuse?

I think that you lack any technical acumen and your bluster
is your attempt to cover up.

Really? For your recent posts have been full of your obsession that the
badge of paedophilia was attached to you, but it was not put there by me,
nor by any real person.

Therefore, it is a truism that you are obsessed by paedophilia, as, indeed,
you quote yourself abive.

I am unsure of US TV. In the UK terrestrial TV is all digital.
Analog(ue) was switched off a few years ago.
I am referring to the whole box from antenna to screen, most of our TVs
come with built-in 'Freeview'.

I have a digital set about 6 years old that struggles to handle complex
images but my new toy handles it perfectly. My newer TV uses a newer
chipset and more efficient decoding algorithm that is made possible
because of the higher power chipset.

The older chipsets are still in production and still being sold,
presumably the TV manufacturers can buy them cheaply, stick them in the
TV and rely on marketing buzz over technical demonstration to sell then
for a larger markup. Most people I know buy on screen size anyway.

My understanding - which may be incorrect - is that the TV has a fixed
time based upon the framerate in which to decode the image and display
it before it has to start on the next frame.
Better quality TVs are capable of fully decompressing the image and
displaying it between frames but the cheaper and older ones cannot
handle a new image every frame and so, when it runs out of time decoding
the image it just gets sent to the screen, tesselations and all.
Standing ready to be corrected.

Andy,

here in the United States, everything is digital also, and has been for
years (here come the trolls).

Yes, the TV only has a certain amount of time to decode the signal. But
in the U.S., the method used is proprietary to one company. The
chipsets required to decode the signal are all produced by this company,
so all TV's have similar decoding.


I think you are confusing all chip makers using the same algorithm with
all TV makers buying their chips from the same chip maker.

Are you suggesting that all of these chip makers are reselling one
company's products?

The decoding is very much *not* proprietary to one company. There is a
consortium of companies who own patents for the MPEG-2 decoder alone...

If you would bother to understand what you referenced, NONE of these
chipsets are hi-def (1080).

And yes, H.264 is a proprietary algorithm, with only one company
providing the chipsets.

The decoding is very much *not* proprietary to one company. There is a

http://www.mpegla.com/main/programs/...ts/m2-att1.pdf


Once again you show you don't understand the technology, but have to
argue anyway. MPEG-2 is NOT H.264.

http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

begin quote
A hardware H.264 encoder can be an ASIC or an FPGA.

ASIC encoders with H.264 encoder functionality are available from many
different semiconductor companies, but the core design used in the ASIC
is typically licensed from one of a few companies such as Chips&Media,
Allegro DVT, On2 (formerly Hantro, acquired by Google), Imagination
Technologies, NGCodec. Some companies have both FPGA and ASIC product
offerings.[56]

Texas Instruments manufactures a line of ARM + DSP cores that perform
DSP H.264 BP encoding 1080p at 30fps.[57] This permits flexibility
with respect to codecs (which are implemented as highly optimized DSP
code) while being more efficient than software on a generic CPU.
