Question

which of the following amplifier has poorest efficiency.
a. Class
D
O b. Class C
O c. Class B
O d. Class A​

Answer 1

Answer:

A

Explanation:

Class A amplifier has the highest linearity and the lowest distortion. The amplifying element is always conducting and close to the linear portion of its transconductance curve. The point where the device is almost off is not at a zero signal point and hence its distortions compared to other classes are less.
