In the circuit given in the figure, since
Vi is a square wave with a frequency of 1 kHz and an amplitude varying between +5V and -5V;
Vi and Vo voltages one after the other and in scale;
a) Draw with Zener diode is not active ?
b) Draw with the Zener diode on?
(Assume the diodes in the circuit are ideal)
