Edition 2ISBN: 978-0766826847 Exercise 34
Suppose a receiver has the following gain structure (and that all stages are operating at maximum 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 both in watts and in microvolts, assuming a 50 input impedance.
(c) Now suppose a 100 mV signal is applied to the antenna. Calculate the output power. Is this a reasonable answer Explain why or why not. What would actually happen in a real receiver
