Class_____________ power amplifier has the highest collector efficiency ?
Correct answer: A. C
- A. C
- B. A
- C. B
- D. AB
Explanation
Class C has the highest theoretical collector efficiency because its transistor conducts for less than 180 degrees and a tuned circuit reconstructs the output waveform. Its poor linearity prevents direct use for faithful audio amplification.
