In radio and signal processing, heterodyning is the generation of new
frequencies by mixing (multiplying) two
oscillating waveforms. It is useful for placing information of interest into
a useful frequency range following modulation or prior to demodulation . The two frequencies are mixed in a vacuum tube ,transistor , diode, or other
signal processing device. Mixing two frequencies creates two new frequencies, according to the properties of the sine function; one is the sum
of the two frequencies mixed, the other is their difference. These new frequencies are called heterodynes . Typically only one of the new
frequencies is desired—the higher one after modulation and the lower one after demodulation. The other signal is filtered out of the output of the

There's a description of what. Two different signals.

Look at the last sentence in the description. I know the gist of what you were going to say, but you didn't finish it.
