### Clipper & Clamper Interview Question Answer

 1 What is clipper circuit? Clipper circuit It is circuit which cut or clips the portion of the applied waveform. 2 Describe the different types of clipper circuit. Types of clipper circuit Positive clipper Negative clipper Biased clipper Combination clipper 3 Which circuit parameter the clipper circuit consists of? Positive and negative clipper   Resistance and diode Biased and combination clipper Resistance, diode and battery 4 Explain the term : Positive clipper, Negative clipper, Biased clipper and Combination clipper Positive clipper It is clipper which cut the positive half of the input alternating waveform. Negative clipper It is clipper which cut the negative half of the input alternating waveform. Biased clipper It is clipper which cut or clips the positive or negative half of the input alternating waveform. 5 Explain the term : Biased positive, Biased negative clipper and combination clipper Biased positive clipper If there is only small portion of the positive half cycle clip and negative half cycle will applied across the load, it is called as biased positive clipper. Biased negative clipper If there is only small portion of the negative half cycle clip and positive half cycle will applied across the load, it is called as biased negative clipper. Combination clipper It is combination of biased positive and biased negative clipper. 6 State the application of the clipper circuit. Application of clipper Electronic circuit Digital circuit and Radar 7 What is operating principle of the Clamper circuit? Principle of Clamper circuit The clamper circuit operates on the principle that the charging time of the capacitor is very small as compared to discharging time. 8 Describe the function of the Clamper circuit. Function of Clamper circuit The function of the clamper circuit is to raise the positive or negative peak value at a desirable level. It does not change peak to peak value of the signal. It only changes the DC level of the signal. 9 Whether the original signal change at the output of the Clamper circuit? No, the original signal does not change at the output of the clamper circuit. 10 What is meaning of the Positive Clamper and Negative Clamper? Positive Clamper The function of the positive clamper is to raise the input signal to upward direction such that negative peaks falls to zero. Negative Clamper The function of the negative clamper is to raise the input signal to downward direction such that positive peaks fall to zero.
