Question: What is the primary function of a bypass capacitor in a BJT amplifier?

Options:

  1. To increase the input impedance
  2. To reduce noise
  3. To stabilize the bias point
  4. To improve frequency response

Correct Answer: To improve frequency response

Solution:

A bypass capacitor improves the frequency response of a BJT amplifier by allowing AC signals to bypass the emitter resistor.
