S/N and (S+N)/N When measuring signal to noise ratio there are two basic elements to the measurement. One is the noise level and the other is the signal. As a result of the way measurements are made, often the signal measurement also includes noise as well, i.e. it is a signal plus noise measurement.
Since our modulating frequency to carrier frequency ratio (mc-ratio above) is 1.0, we get sidebands at harmonics of the carrier. If we use an mc-ratio of .25 and a carrier of 400: we end up with the same perceived pitch because the sidebands are still at multiples of 100 Hz. has inharmonic sidebands.
