WebThe LM1596/LM1496 are doubled balanced modulator-de-modulators which produce an output voltage proportional to the product of an input (signal) voltage and a switching (car-rier) signal. Typical applications include suppressed carrier modulation, amplitude modulation, synchronous detection, FM or PM detection, broadband frequency doubling … WebThe phase of a carrier wave is varied in response to the vibrations of the sound source in phase modulation (PM). This form of modulation is often considered a variation of FM. The two processes are closely related, because phase cannot be changed without also varying frequency and vice versa.
