The detector in your basic AM radio is much the same as it has been for
nearly 100 years now. It rectifies one half of the envelope and filters
out
the remaining RF to leave an audio waveform. It does not detect both
halves (both sidebands) of the waveform. This is why such things as
selectable
sideband make high end radios better able to pick out a signal. The
signal with both sidebands may be applied to the detector, but it's not
what comes out. I stand by my question. If only one sideband is actually
detected, there can be no phase cancellation.


You clearly don't understand how an AM detector works.


But I do. The basic AM detector works exactly as any half-wave rectifier. If
you used a full-wave rectification, then you could detect both sides of the
RF waveform, but logic would seem to dictate that this would cancel the
audio waveform, since the two sidebands are mirror images of one another.
