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

Question 1
Analog ElectronicsWaveform Generators

A monostable multivibrator has how many stable states?

  • AZero
  • BOne
  • CTwo
  • DFour
Report an error
Correct Answer: B. One
Explanation: A monostable circuit has one stable state and one temporary quasi-stable state entered after triggering.
Reference: Standard analog electronics: monostable multivibrator
Question 2
Analog ElectronicsWaveform Generators

An astable multivibrator is characterized by?

  • ANo stable state and continuous self-oscillation
  • BExactly one stable state
  • CTwo stable states with no automatic transitions
  • DA fixed DC output only
Report an error
Correct Answer: A. No stable state and continuous self-oscillation
Explanation: An astable multivibrator has no stable state and continuously alternates between two states, generating a periodic waveform.
Reference: Standard analog electronics: astable multivibrator
Question 3
Analog ElectronicsWaveform Generators

A bistable multivibrator has?

  • ANo stable states
  • BOne stable state
  • CTwo stable states
  • DThree stable states
Report an error
Correct Answer: C. Two stable states
Explanation: A bistable circuit can remain indefinitely in either of two stable states until an external trigger causes a transition.
Reference: Standard analog electronics: bistable multivibrator
