Question A-006-001-001

What are the advantages of the frequency conversion process in a superheterodyne receiver?

Correct Answer

Increased selectivity and optimal tuned circuit design

Explanation

Frequency conversion to a fixed Intermediate Frequency (IF) allows most of the receiver's gain and selectivity to be achieved in IF amplifier stages that operate at a constant, optimal frequency, simplifying design and improving performance.
