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.
