Consider the following limiter circuit an input voltage V| = 10.5 sinlOOnt is applied. Assume that the diode drop is 0.7 V in forward bias. The zener breakdown voltage is 6.3 V.

The maximum and minimum values of the output voltage respectively are

Detailed Solution for Test: Analog & Digital Electronics - 1 - Question 2

For +ve value of Vi, D1 is F.B and zener diode regulates the voltage at 6.3 V across it.
V0 = 6.3 + 0.7 = 7 V
and for negative half of V:, D2 is forward biased.
'    V0 = -0.7 V
