1. Determine vo for each network of shown below for the input shown.

Ans:-

2. Determine vo for each network of Fig shown below for the input shown






Ans:-

3. Determine vo for each network of

Ans:-






4. Determine vo for each network of as given beolw with the input shown.

Ans:-






5. Sketch iR and vo for the network of as shown below for the input shown.






6. Sketch vo for each network shown below for the input shown.






Ans

7. Sketch vo for each network as given below for the input shown. Would it be a good approximation to consider the diode to be ideal for both configurations? Why? Ans:-






8. For the network of given below (a) Calculate 5. (b) Compare 5 to half the period of the applied signal. (c) Sketch vo.

Ans:-






9. Design a clamper to perform the function indicated in

Ans:- From the output waveform, we understand that ,it is a positive clamper with negative biasing As shift is Vomax –Vinmax = 10V So Vdc = Vinm – shift = 20-10 =10V dc






10. Design a clamper to perform the function indicated as below

Ans:- From the output waveform, we understand that ,it is a negative clamper with positive biasing As downward shift is 10-2.7 = 7.3V Vdc = Vm- Vshift – Vd = 10 -7.3V - 0 .7 = 2 V dc Clamper circuit is
