Hmmm... that's what I thought originally. Now I'm getting confused. I'm
real interested how this discussion shakes out...

Do not listen to him, it is 100% nonsense.

Very simply:
An AM detector is an 'enveloppe' detector,
a DSB and SSB detector is a 'product detector'.

You have seen that waveform I pointed out in fig 4 for a sine wave single
tone modulation, the amplitude of the RF signal dos not really look like a
sinewave does it?

So you hear sever distortion, in fact you cannot make out what it is.

In a product detector the BFO is the 'substitute' carrier, and multiplication
of one (SSB) or both (DSB) sideband[s] gives the original modulation.

There is in fact no need for the 'other' sideband in DSB-SC, no problem if
the receiver filters it out, that is why you can receive DSB-SC both with
USB and LSB!

But for the non-believers, try it out, all you need is an audio amp,
oscillator, 4 diodes, and of course a 27 HHz xtal oscillator.

There is a description and diagram a bit down on the page.

Listen to it on an AM receiver, and you will KNOW.
