Clippers & Clampers MCQs

Practice Clippers & Clampers MCQs with four options, answers and explanations for focused Electronics & Telecommunication Engineering revision.

Question 1
Electronic Devices & CircuitsClippers & Clampers

In a positive biased diode clipper, the clipping level is primarily determined by?

  • AOnly the input frequency
  • BThe bias voltage together with the diode forward drop
  • COnly the load resistance
  • DThe transistor beta
Report an error
Correct Answer: B. The bias voltage together with the diode forward drop
Explanation: In a biased clipper, conduction begins when the input reaches a level set by the DC bias plus or minus the diode forward drop, depending on circuit orientation.
Reference: Standard wave-shaping circuits: biased clipper
Question 2
Electronic Devices & CircuitsClippers & Clampers

An ideal clamper circuit is primarily used to?

  • AChange the DC level of a waveform without ideally changing its peak-to-peak value
  • BAmplify power by a factor of 100
  • CConvert every sine wave into DC
  • DIncrease frequency
Report an error
Correct Answer: A. Change the DC level of a waveform without ideally changing its peak-to-peak value
Explanation: A clamper shifts a waveform vertically by adding a DC component while ideally retaining the waveform shape and peak-to-peak amplitude.
