Factors for sensitivity of super heterodyne receiver

The factors that determine the sensitivity of super heterodyne receiver are

Options:

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

Correct Answer: All of the above

Explanation:

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
