The only info I had until recently is with AM, the audio freqeuncy is superimposed on the carrier wave. I figured that the amplitude of a single frequency was varied and that was it. Now I read that side bands are always produced but not all AM modulators have a mixer. Simple AM modulators only have a oscillator ,a transformer , mic , battery and a antenna. I doubt that this set up can create side bands. Would someone please point me in the right direction on this?
