This set of Analog Circuits Multiple Choice Questions & Answers (MCQs) focuses on “Series 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)
a) 
b) 
c) 
d) 
View Answer
Explanation: In the circuit of serial clipper, it clips the negative half cycle and the output will only contain positive half cycle. In this problem input is a sine wave, hence output will be positive 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)
a)
b)
c)
d) 
View Answer
Explanation: In the circuit of serial clipper, it clips the negative half cycle and the output will only contain positive half cycle. In this problem input is a triangular wave, hence output will be positive half of triangular 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)
a)
b)
c) 
d) 
View Answer
Explanation: In the circuit of serial clipper, it clips the negative half cycle and the output will only contain positive half cycle. In this problem input is a square wave, hence output will be positive half of square wave.
4. A simple circuit diagram for a serial clipper is given below. What will be the transfer characteristics of the circuit?
(Use constant voltage drop model of diode)
a) 
b) 
c) 
d) 
View Answer
Explanation: Since at constant voltage drop model voltage drop across diode at forward bias is a constant. In this circuit if input is negative diode is reverse bias hence no current. So for negative input output is zero. For positive input Vout will be equal to input with a voltage drop of VD.
