Questions and Answers

What is the primary function of feedback in an oscillator circuit?

  • To introduce phase shift to the input signal
  • To sustain oscillations by providing a fraction of the output signal back to the input (correct)
  • To amplify the input signal to maintain oscillations
  • To attenuate the input signal to prevent oscillations

What type of oscillator uses a resonant circuit to generate a sinusoidal waveform?

  • LC oscillator (correct)
  • Relaxation oscillator
  • Crystal oscillator
  • RC oscillator

What is the significance of the Barkhausen criteria in oscillator design?

  • It determines the bandwidth of the oscillator
  • It defines the conditions for oscillation in electronic circuits (correct)
  • It calculates the power dissipation of the oscillator
  • It specifies the voltage regulation of the oscillator
