ROFLMAO! I take that back. Even a third grader would know it was
neither clever nor mature. You don't even reach that level.

"ROFLMAO!"? Talk about third grade mentality. That stupid **** was out
ten years ago, child.

Nice try though, STUCKLETT. Bwuahahahahaa!

I have nine inches of respectability to go up in your wussy ass with,

No lie at all. Quite easy to find.

The fact that you spent your personal time "hunting up" info on
another poster proves that you are the troll. A quite immature one at
that. Nice try though, punk. Waste more of your personal time.

I know what usenet is.

Obviously not. It is capitalized, for starters.

That doesn't mean that others in other
newsgroups want you.

You obviously cannot read. Remember the part where I told you I do
not give a **** what zero IQ dolts like you think?

And from the posts I found, it's quite obvious you
are not wanted in a number of newsgroups.

It is obvious that you like wasting your personal time mentally
masturbating. You are hilarious to watch lose though.

Still with the decades outdated gang boy retard lingo...

Now you go running back to your mommy and tell here the mean old guy

==================
Remove the "x" from my email address

You mean like this...



Too pussified to post it? Don't code it in either idiot.

Wake up, little suzzie. Oh that's right... you are as awake as an
idiot with only two functioning neurons can be. Good job, jackass.


Ah, another troll who needs psychiatric help. Only ones like you would
try to purposely get someone spammed.

An idiot like you needs just that. Have a nice life, thread invading
punk.

You really need to have your mommy take you to a shrink.

My mother would want me to take a punk like you out to the desert and
bury you up to your neck next to an ant hill.

Your mother should be in prison for failing to flush the piece of ****
you are, the moment the retarded slut shat you.

Rickman asked you dumb****s to stop, and you came back with a PKB
insult for him, and you haven't shut the **** up since.

And you call me a troll.

I just don't like SPAM.

No, you obviously like BEING the SPAM, as you were asked to leave it
OUT of this thread, and you haven't shut the **** up since.

However, I at least use an email address which
is easily decoded (read CAPTCHA), unlike the non-existent email address
you use.

There is a reason I do not post my email in Usenet, idiot.

What are you afraid of - maybe your mommy might find out what crap
you're posting on usenet?

When a punk like you says "crap" it is ok.. When I say it, I get
accused of having a fetish. George Carlin has a joke just for retarded
dorks like you.

Give it up

Give what up, you retarded troll ****?

- you have zero respectability on usenet

The term is Usenet, idiot.

. - here or anywhere
else I've found.

The fact that you spend your personal time "hunting things up" on
Usenet is an indicator of some serious psychological disorders, child.

But then that's expected from someone less mature than
a third-grader who needs serious psychiatric help.

You keep referring to psychiatry.. Were you given drugs, Jerome?

I hope your mommy gets it for you. You will be much happier.

Nice try, little boy. Your mental age is showing... again.

I read this post in an antenna group and I don't get how this guy is
coming up with a negative noise figure. Looks to me like he is
calculating the noise figure of a resistor, not the amplifier. Anyone
care to explain this to me?

The part that seems bogus is this...

The negative NF is defined as the amplifier noise being less than the
increase in noise due to the amplifier gain.

I thought noise figure was NF = SNRin / SNRout

Rick


Both definitions are correct and mean the same thing; a negative NF,
when expressed in dB, would be when the SNRout is less than the SNRin.
However, the big but is that an negative NF is not possible.

I don't think both definitions mean the same thing. If the amplifier
adds *any* noise it increases the NF above zero by the conventional
definition. The only way the NF can be negative is if the amplifier
removes noise from the input, or in other words, increases the SNR.


Yes that is correct, but the definitions are also correct. The flaw in
the negative noise figure argument is that it is not possible to have a
better SNRout than SNRin *for the same system conditions*.

The apparent negative noise figure only come about by comparing the NF
of the amp in a 50ohm system with the output from a system with
something different on the input.

The test method used is also very prone to measurement errors for low
noise figures.

Jeff

To me, NF refers to "noise floor".

It probably would to an utter imbecile such as you.


Lets see him go below that.

GPS received signals are among the lowest "power" signals we currently
grab. They sit just above the noise floor.

That makes complete sense, furball for brains.

Sounds like you looked in the mirror, asswipe.

You're projecting again, Furball.

Can you two find another thread to post your silly insults in? Why
don't you start a new thread all about how much you guys like to bicker?

Pot-Kettle-Black

Wrong, Stucklett. Rickman has attacked no one.


ROFLMAO! Another troll heard from.

You're an abject idiot, child.


You're the one with the third grade name calling. Your mommy should
wash your mouth out with soap.

And this is even a third grader -
from the immature name calling.

No. The name used was quite clever and mature, unlike the lies you
are about to spout.


ROFLMAO! I take that back. Even a third grader would know it was
neither clever nor mature. You don't even reach that level.

And one who can't read, either.

I read fine, putz. Why are you even in this thread? Oh... that's
right... to stir ****.


You don't read at all.

But then it's only what one expects from a no-name troll.

I have a name.. Just not for retarded putz jackasses like you.


No, you're only a nameless troll. You have no respectability here or in
other newsgroups.

How many
other groups are you known for trolling?

Not a troll, dumb****.

I found a half dozen in less
than a minute...

Major lie. The only time I *ever* post outside the two groups I
subscribe to is when a retard not unlike yourself decides to cross-post.

No lie at all. Quite easy to find.


Why not go back to sci.electronics.design?

I never left, you retarded dumb****. The OP is also from there. he
merely posted here because it was thought that *some* of you might have
an IQ above 12..


Unfortunately, you don't.

Or don't they want you, either?

This is Usenet, you zero brained dumb****. I do not give a fat flying
**** what you or anyone else in this realm "wants", and you are far too
stupid to make assessments, as evidenced by the post you made, which I
responded to. Then you chimed in with this childish baby bull****.


I know what usenet is. That doesn't mean that others in other
newsgroups want you. And from the posts I found, it's quite obvious you
are not wanted in a number of newsgroups.

You also can't proofread the horse**** you spew.

Good effort Jerry! You scored a five-er. Even seasoned DimBulb baiters
seldom achieve that. Well done!
