Wave-Shaping Circuits MCQs

Practice Wave-Shaping Circuits MCQs with four options, answers and explanations for focused Electronics & Telecommunication Engineering revision.

Question 1
Analog ElectronicsWave-Shaping Circuits

A clamper circuit primarily changes which property of a waveform while ideally preserving its peak-to-peak value?

  • AIts DC level
  • BIts frequency
  • CIts harmonic order only
  • DIts source resistance only
Report an error
Correct Answer: A. Its DC level
Explanation: A clamper shifts the entire waveform upward or downward by adding a DC component while ideally retaining the original peak-to-peak amplitude.
Reference: Standard analog electronics: clamper circuit
Question 3
Analog ElectronicsWave-Shaping Circuits

A diode limiter is commonly used in analog circuits to?

  • ARestrict signal amplitude beyond selected levels
  • BIncrease all signal amplitudes linearly
  • CGenerate a constant current mirror
  • DProvide galvanic isolation
Report an error
Correct Answer: A. Restrict signal amplitude beyond selected levels
Explanation: Limiter or clipper circuits use diode conduction to constrain waveform excursions above or below chosen threshold levels.
