Question

Suppose that the amplifier as shown has been
designed to match the source and load resistances
with the parameters below. (a) What is the amplitude
of the input signal vi needed to deliver 1 W
to the 16- load resistor? (b) How much power is
dissipated in the amplifier when 1Wis delivered to
the load resistor?
Input resistance Rin = 1 k
Output resistance Rout = 16
A = 50 dB
