  1. Transformer and emitter follower can both be used for impedance matching at the output of an audio amplifier. The basic relationship between the input power Pin and output power Pout in both the cases is
    1. Pin = Pout for both transformer and emitter follower
    2. Pin > Pout for both transformer and emitter follower
    3. Pin < Pout for transformer and Pin = Pout for emitter follower
    4. Pin = Pout for transformer and Pin < Pout emitter follower
Correct Option: A

NA
