Your attempts at presumed humor, are as bad as your AM knowledge. :^)

By the way, I looked at the wiki link you posted and I can see why you are
misinformed by it; it's author was either simply not clear in his own mind,
or he did not understand that the "undulations" on the telephone line DC
voltage is NOT amplitude modulation in the multiplier sense. It is not AM
as it is being discussed in this thread of Radium's original post. If you
prefer the math proof, multiply the DC voltage frequency (0) by the audio
frequency (pick a number between 200 and 3000 Hz), and the product is zero -
No new frequencies are present. There's more to it than that but I probably
already lost you.

You're both wrong. It is VIRTUAL SIDEBAND because it isn't completely
real and the other sideband which isn't virtual carries the missing high
frequency modulation info. Once it gets into your second detector then
it becomes real due to the laws of product modulation.
Next, you will be telling people that VGA doesn't stand for "virtual
graphics array."

NO modulation at all, krist, the guy on the other end is only carrying
on a "virtual conversation!"
Excellent use of logic, keep up the good work ...

But I know WHY the plate modulated rig creates sidebands, and you still
don't, because you refuse to learn.

Interesting, now you attempt to divert the conversation into the
modulation having been, FINALLY, impressed into the sidebands ...
Hell, it was just such a chore bringing your education up to speed on
this one point, I'd have to be paid to continue your education!

You allude to knowing how the sidebands come into being yet you cannot
provide any clue that you really understand AM, and you continue to think
microphone current in a telephone loop is the same thing. You're as FOS as
they come.
I doubt you have fooled anyone on this board with your attempts to look like
you know more than you really do.

Buddy, you speak about these people being "fooled", interesting term,
implying you consider them fools!
I doubt that is true, they have seen through you in a heartbeat, most,
probably long before now ... I imagine they are just embarrassed for
you--having made such an A$$ of yourself ...

Please point out, above, or wherever you wish, where I said they were
fooled. You can't you POS liar.

While you continue to allude to skills and knowledge you don't have.
Do you often get away with this useless chest beating?

You pathetically petty idiot ... I guess you call names because of your
age. Or, others have called you names and it has hurt your ego. Get an
education, grow-up and get off the drugs--you will be able to finally
respect yourself! :-(
Best hope in your therapy!

But POS was intended for guys like you.
Ok! Again, you win. Please enjoy your blissful ignorance with my good

Suppose you have a 1 MHz sine wave whose amplitude

What would it look like on an oscilloscope?
What would it look like on a spectrum analyzer?
Then suppose you have a 1.1 MHz sine wave added

What would that look like on an oscilloscope?
