Radio Receivers - Engineering

Q1:

Fidelity of a receiver represents

A the sensitivity expressed in terms of voltage that must be applied to the receiver input to give a standard output

B the extent to which the receiver is capable of distinguishing between the desired signal and other frequencies

C the variation of the output with the modulation frequency when the output impedance is a resistance

D none of the above

ANS:C - the variation of the output with the modulation frequency when the output impedance is a resistance

The answer is D.

The ability of the receiver to reproduce exact replica of the transmitted signal or input signal
