Answer to Question #114168 in Electric Circuits for Simran Yadav

Question

In case of a receiver explain the following terms with the help of graphs: (i) linearity and (ii) fidelity. What should be
their ideal behaviour/value?

Answer 1

(I)The linearity of the receiver is best summarized in the concept of Equivalent Input Intercept Point of the receiver . This parameter takes into consideration the effect of non-linearity of every stage in the receiver, including amplifiers, mixers, and filters.

(II)The steepness of the response curve at the tuned frequency indicates the selectivity of the receiver. Fidelity The fidelity of a receiver is its ability to accurately reproduce, in its output, the signal that appears at its input.
