Question

What is the advantage of superheterodyning?

(a) High selectivity and sensitivity

(b) Low Bandwidth

(c) Low adjacent channel rejection

(d) Low fidelity

The question was asked in an interview.

I would like to ask this question from Channel in section Elements of Communication System of Analog Communications

Answer 1

Correct option is (a) High selectivity and sensitivity

To explain I would say: The main advantage of superheterodyning is that it provides high selectivity and sensitivity. It’s bandwidth remains same. It has high adjacent channel rejection and high fidelity.
