I read on a website that in amplitude modulation the actual carrier wave does not change its amplitude but rather the sidebands.

Is this true

Y(t)=(A+Bcos(ωt))cos(Ωt)=Acos(Ωt)+Bcos(ωt)cos(Ωt).

Using the identity cos(a+b)+cos(a-b)=2cos(a)cos(b), the second term can be written as B/2(cos((Ω+ω)t)+B/2(cos((Ω-ω)t).

The modulated wave consist of the carrier with the original amplitude and two side-bands with half the amplitude of the modulating signal.

Well, if you read it on a website, then it must be true.

Is this true

If you watch the waveform on an oscilloscope, you see the amplitude varying, just as the title implies. But if you watch the display on a
