S$-1)$ In the circuit given below, a clipper circuit is connected to the clamper output and C$=100$ nF is given in the circuit. According to the Vi signal shown in the figure and whose frequency is f$=12$ KHz$,$ is applied to the input of the circuit;

a$)$ What should be the minimum value of the R resistor so that the input signal can be received from the circuit output without distortion $($excluding clipping$)?$

b$)$ Draw the output waveform for $5$RC$>>$T$/2$ and show the voltage values $$on the figure.
