Selectivity of a receiver & Advantages of an RF amplifier
Q. Selectivity of a receiver:- Published on 14 Oct 15a. Changes with incoming signal frequency
b. Is poorer at high frequencies
c. Is the rejection of the adjacent channel at the receiver
d. All of the above
ANSWER: All of the above
The ability of the receiver to select the wanted signals among the various incoming signals is termed as Selectivity. It rejects the other signals at closely lying frequencies. Selectivity is determines performance of a radio receiver that how much it responds only to the radio signal that is required to receive. Selectivity of a receiver changes with incoming signal frequency and is poorer at high frequencies
