Consider the following components in a multi-stage R-C coupled amplifier: 1. Parasitic capacitance of transistor 2. Coupling capacitance 3. Stray capacitance 4. Wiring capacitance Which of the above components effectively control high frequencies? Correct Answer 1, 3 and 4

  • RC Compled amplificr is two stage coupled cmplifier.
  • Output of one amplifier is coupled to the next amplifier with the help of coupling capacitor.
  • RC – Coupled amplifier is used for audio frequency signals.
  • The low frequency control is done by coupling capacitor but for high frequency control, parasitic, stray & wiring capacitors are effectively work.
