250+ TOP MCQs on Parallel Clipper-1 and Answers

Analog Circuits Multiple Choice Questions on “Parallel Clipper-1”.

1. For a circuit given below, what will be the output if input signal is a sine wave shown below.
(Use ideal diode model of diode)

Answer: D
Clarification: In this circuit of parallel clipper, diode conducts the half cycle when it is positive and the output will only contain negative half cycle. In this problem input is a sine wave, hence output will be negative half of sine wave.

2. For a circuit given below, what will be the output if input signal is a triangular wave shown below.
(Use ideal diode model of diode)

Answer: A
Clarification: In this circuit of parallel clipper, diode conducts the half cycle when it is positive and the output will only contain negative half cycle. In this problem input is a triangular wave, hence output will be negative half of that wave.

3. For a circuit given below, what will be the output if input signal is a square wave shown below.
(Use ideal diode model of diode)

Answer: C
Clarification: In this circuit of parallel clipper, diode conducts the half cycle when it is positive and the output will only contain negative half cycle. In this problem input is a square wave, hence output will be negative half of that wave.

4. A simple circuit diagram for a parallel clipper is given below. What will be the approximate transfer characteristics of the circuit?
(Use ideal diode model of diode)

Answer: D
Clarification: The above is a parallel clipper with an ideal diode model, so whenever the input is in its negative cycle, it will come as the output as the diode will then not conduct. When positive, diode conducts and output is zero.

5. For a circuit given below, what will be the output if input signal is a sine wave shown below.
(Use ideal diode model of diode)

Answer: C
Clarification: In this circuit of parallel clipper, diode conducts whenever the input cycle is the negative half cycle and thus output will only contain positive half cycle. In this problem, input is a sine wave, hence output will be positive half of sine wave.
