Laquelle des classes d'amplification cidessous procure le rendement le plus élevé?

  1. ALa classe B
  2. BLa classe C
  3. CLa classe A
  4. DLa classe AB

Correct answer: B — La classe C. Question tirée de la banque officielle d'ISDE.

Why

Class C amplifiers achieve the highest efficiency because the active device conducts for less than half of the input signal cycle, meaning it spends most of its time turned off and wasting very little power as heat. The full explanation — and one for every question — is in Pro.
