چکیده:

In this article we study simple amplitude and balanced amplitude modulators and compare the result of them. Both of them can produce the standard amplitude modulation signal. The simple amplitude modulator has one bipolar transistor and it has upper THD , lower DC gain and lower generative power. But the balanced amplitude modulator is structured of the differential stage of bipolar transistors and it has lower THD , upper DC gain and upper generative power and these are important advantages for this modulator
