  • Answered by AI
  • Q11. Why common emitter is also called as inverter?
  • Ans. 

    Common emitter is called an inverter because it produces an output that is the opposite of the input signal.

    • In a common emitter configuration, the output signal is 180 degrees out of phase with the input signal.

    • The common emitter amplifier produces a phase shift of 180 degrees, effectively inverting the input signal.

    • This inversion property is why the common emitter amplifier is also known as an inverter.

  • Answered by AI
  • Q12. Which configuration of transistor is called as buffer and why?
  • Ans. 

    A transistor configuration with high input impedance and low output impedance is called a buffer.
