Construct the diode rectification circuit shown in Figure $3,$ with the capacitor

disconnected. Use signal generator as a$.$c$.$ source to provide sine wave with $1$ kHz and

amplitude $5$ V $.$ View the voltage waveform across the resistor with an oscilloscope.

Connect a $0\mathrm{.}1$ muF capacitor across the resistor. Observe the change in the waveform

shape, and explain what happens. Predict what will happen if a larger value of

capacitance $($say $100$ muF $)$ is connected across the resistor.

Construct the diode clipping circuit shown in Figure $4,$ investigate the function of the

circuit by varying the DC power supply SLOWLY from $0$ V to $5$ V and the signal

generator. Observe the change in the waveform shape and explain what happens.

Further Work

Design a diode clipping which clips at a voltage level of around $1\mathrm{.}2$ V $.$ By using suitable

waveforms from the signal generator and by observing the output waveform, test the

characteristic of your circuit.

Design a full$-$wave rectification circuit. Explain the design briefly.
