Analog ElectronicsFrequency Response

The lower cutoff frequency of an RC-coupled amplifier is mainly influenced by?

  • ACoupling and bypass capacitors
  • BTransistor breakdown voltage only
  • CPower-supply frequency only
  • DCollector color code
Report an error
Correct Answer: A. Coupling and bypass capacitors
Explanation: At low frequencies, coupling and emitter-bypass capacitor reactances become significant and reduce gain.
