Question
I only need answer for letter C. Thanks
![Suppose a receiver has the following gain structure (all stages operating
at maximum gain):
12 dB gain
1 dB loss
76 dB gain
RF amp:
Mixer:
IF amp:
Detector:
3 dB loss
Audio amp: 35 dB gain
(a) What is the total power gain of the receiver from antenna to
speaker?
(b) What would be the minimum signal required at the antenna in
order to get a power of 0.5 W into the speaker? Express your answer
in both watts and microvolts, assuming a 50-2 input impedance.
