Expression for over all noise figure of a mismatched amplifier is:

Expression for over all noise figure of a mismatched amplifier is: Correct Answer 1+ (F-1)/ (1 -│Г│2)

The overall noise figure of a mismatched amplifier is given by 1+ (F-1)/ (1 -│Г│2). Here F is the noise figure of the amplifier, when there is an impedance mismatch at the input of the amplifier; this impedance mismatch is given by Г.
