Assuming the diodes to be ideal in the figure, for the output

Assuming the diodes to be ideal in the figure, for the output to be clipped, the input voltage v_i must be outside the range

1. – 1 V to – 2 V
2. – 2 V to – 4 V
3. + 1 V to – 2 V
4. + 2 V to – 4 V

Correct Option: B

When 2V > V_AB > – 1V
Then D₁ and D₂ will be ON
and V_o = – 2 volt.
For D₁ to be OFF,
V_AB < – 1 V
For D₂ to be OFF,
V_AB > – 2 V
then, for – 1 V > V_AB > – 2V
both D₁ and D₂ will be OFF and output voltage will not be clipped.

and, V_o =	V_i	. 10 =	V_i
	10 + 10		2

For output voltage not to be clipped, the condition is ,

-1 V >	V_i	> - 2 V
	2

⇒ - 2 v > V_i > - 4 V
Hence, for output voltage to be clipped, input voltage Vi must lie outside the range of
– 2 V > V_i > – 4V
