The dominant low-frequency cutoff of a capacitively coupled transistor amplifier is commonly influenced by?

  • ACoupling and bypass capacitors with the resistances they see
  • BTransistor transit time only
  • CJunction breakdown voltage only
  • DCollector power rating only

Correct Answer: A. Coupling and bypass capacitors with the resistances they see
Explanation: At low frequencies, coupling and emitter/source bypass capacitors have larger reactance, creating high-pass poles that determine the low-frequency response.
Reference: Standard analog electronics: low-frequency response
