Silicon diode — UPSC Physics Optional CSE 1997 Paper II

Four silicon diodes are connected as shown in Fig. 1. A sinusoidal voltage of amplitude 2\text{ V} is applied in the input. What is the waveshape of the output and its amplitude? If the amplitude of the input voltage is reduced to 1\text{ V}, what will be the waveshape of the output and its amplitude ? Threshold voltage of each diode is 0.6\text{ V}.
