In a superheterodyne receiver the bulk of the receiver's sensitivity and selectivity is due to the:
A) IF amplifier stages.
B) local oscillator.
C) converter stages.
D) RF amplifier stages.

Question

Quizplus · Accepted Answer

The IF (Intermediate Frequency) amplifier stages in a superheterodyne receiver are primarily responsible for the receiver's sensitivity and selectivity. These stages amplify the signal at a fixed intermediate frequency after it has been mixed down from its original frequency, allowing for more precise filtering and amplification.
