From a source with Pin = 2.4 mW, we want to get Pout = 60 mW at a distance l = 20 km from the source. α for the transmission line is given to be 2.3 dB/km. The available amplifiers have adjustable power gain, but are subject to two limitations: (i) the input signal power must be at least 1 µW to overcome internal noise, and (ii) the output signal power must not be greater than 1 W to avoid nonlinear distortion. Design an appropriate system.
Q. Consider an ampli?er as a voltage source with an internal resistance of 72 . Find the turns ratio of the ideal transformer such that maximum power is delivered when the ampli?e

Quite often an amplifier is used as a component of an amplifier circuit. Consider the amplifier circuit shown in Figure, which contains an amplifier block as an internal component.
Norton's theorem procedure: 1. Remove R L from the circuit. Search I N by shorting links output terminal. 2. Search R N by short-circuit voltage source or open-circuit
