Generation of AM Wave

AM wave is generated by using multiplier IC (product modulator). The input message signal is multiplied with the carrier signal to produce a double side band suppressed carrier wave. Then carrier is injected to produce standard AM wave. The IC used is AD633. It is a low cost analog multiplier IC used to produce standard AM wave. The inputs are message signal, which has to be modulated and a carrier signal. The output wave is an under modulated standard AM wave.
