Question

Discuss the modulator type which has its functions as the one with the diode

operated in a non-linear mode. Support your solution with a diagram.

Switching modulator is similar to the square law modulator. The only difference is that in the square law modulator, the diode is operated in a non-linear mode, whereas, in the switching modulator, the diode has to operate as an ideal switch.
