I am having trouble understanding how this ring modulator works i.e. how it multiplies the input & carrier to give us appropriate output? Any help or guide will bedeeply appreciated. Reference - http://en.wikipedia.org/wiki/Ring_modulation
The use of "multiply" in this instance refers to that when a diode is switched OFF and is, therefore, blocking a signal, that's equivalent to multiplying the signal by zero, and when it's switched ON and the signal is allowed to pass, that's equivalent to multiplying the signal by 1.
