Q.  The factors that determine the sensitivity of super heterodyne receiver are
- Published on 14 Oct 15

a. Gain of the IF amplifier
b. Noise figure of the receiver
c. Gain of RF amplifier
d. All of the above

ANSWER: All of the above
 
Sensitivity of a receiver is defined as the ability of the receiver to amplify weak signals received by the receiver. It is the voltage that must be applied at the input terminals of the receiver to achieve a minimum standard output at the output of the receiver. The factors that determine the sensitivity of super heterodyne receiver are -

- Gain of the IF amplifier
- Noise figure of the receiver
- Gain of RF amplifier
