An amplifier of class AB means its output signal is between the output of class B and A, such that it varies from 180° (class B) to 360° (class A).
How about its efficiency?
A. Efficiency of class AB is in between the efficiency of class A and B, that is from 25% - 78.5%.
B. It is always as efficient as class A (25%).
C. It is always as efficient as class B (78.5%)
D. The efficiency of class AB is the average of the efficiencies of both class A and class B (25% + 78.5%)/2 = 51.75%
