These forms of amplitude modulation, which cannot be demodulated by

the envelope detector, arise from fairly common situations. Although the

broadcast signal is transmitted as a conventional double-sideband AM

wave, the detuning and skywave reflection of the radio will change this

AM signal into one or a combination of the forms shown in the chart.

When there is adjacent channel interference, TV horizontal scanning

harmonics, interference of the carrier frequency and the like, then using

the upper sideband or lower sideband to receive the unaffected sideband

can significantly reduce the interference. This is because these types of

interference usually only affect one sideband of the AM signal, and the

content of AM radio broadcasts exists in two sidebands, in which each

sideband contains the same content.
