A source with equivalent noise temperature Te = 1000 K is followed by a cascade of three amplifiers shown in Table 1.0. Assume a bandwidth is 60 kHz, evaluate the overall noise factor and noise figure of the cascade. In order to get better performance of the amplifier system, you may try to re-arrange the amplifier units. Please prove and justify which arrangement is the best to be chosen.
