Which is not an advantage of diode detectors?
A) They are highly efficient.
B) They develop a readily usable dc voltage for automatic gain control circuits.
C) Power absorbed from the tuned circuit by the diode detector reduces the Q of the tuned circuit.
D) Distortion decreases as the amplitude of the AM signal increases.

Question

Quizplus · Accepted Answer

Diode detectors are known for their efficiency, ability to develop a DC voltage useful for automatic gain control circuits, and decreasing distortion with increasing AM signal amplitude. However, the power absorbed from the tuned circuit by the diode detector, which reduces the Q of the tuned circuit, is considered a disadvantage, not an advantage.
