Question 3
- Draw and label a positive clipping circuit diagram.
- Describe the principle of operation in 3(a).
Observation
(a)
- (b) For the positive half cycle of input, diode is forward biased and short circuited. Hence, output is zero.
For the negative half cycle of input, diode is reversed biased and open circuited, output is same as input.
There are four possible responses to this question displayed below which include:
series positive clipper, series positive clipper with bias, parallel positive clipper and parallel positive clipper with bias. Most of the candidates that attempted this question showed familiarity with the series (without bias) variety.
