Assignment:
Figure shows the block diagram of a superhetrodyne radio receiver. In a test a 20 uV signal was fed from the aerial into the first stage of the receiver, a radio frequency amplifier. This signal is the passed through several stages of the receiver to eventually appear at the input to the AM detector. For the AM detector to work satisfactory it requires a minimum signal level of -3dB(mW). Calculate the required minimum gain of the fifth intermediate amplifier given the data in table.
Provide complete and step by step solution for the question and show calculations and use formulas.
