AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-lowcarrier frequency

John Fields wrote:

log(sin(a))+log(sin(b))

describes the addition of the logarithm of the amplitude of sin(a)
to the logarithm of the amplitude of sin(b), which still produces
only a sum.

That is, no sidebands.

log(x)+log(y)=log(x*y)
