| A sinusoidal voltage of amplitude 15 V is connected between the input terminals of the circuit shown in the figure. Assume that the diodes are ideal. In the output waveform |
 |
A) Positive peaks of the input will be clipped to +12V and negative peaks will be clipped to -6V
B) Positive peaks of the input will be clipped to +6V and negative peaks will be clipped to -12V
C) Positive peaks of the input will be clipped to +12V and negative peaks will be clipped to -12V
D) Positive peaks of the input will be clipped to +6V and negative peaks will be clipped to-6V
Correct Answer: A
Solution :
| for positive cycle \[\operatorname{D}{{ & }_{1}}-\,forward\] \[\operatorname{D}{{ & }_{2}}-\,reverse\] |
| So, \[{{\operatorname{N}}_{0}}=+12\] |
| For negative cycle \[\operatorname{D}{{ & }_{1}}-\,reverse\] \[\operatorname{D}{{ & }_{2}}-\,forward\] |
| So, \[{{\operatorname{V}}_{0}}=-6volt\] |
