ampli¯er that has a noise ¯gure of 9 dB and an available power gain of 15

dB. Calculate the overall noise ¯gure referred to the input. (8)

(ii) A receiver has a noise ¯gure of 12 dB and it is fed by a low noise ampli¯er

that has a gain of 50 dB and a noise temperature of 90 K. Calculate the

noise temperature of the receiver and the overall noise temperature of the

receiving system. Take room temperature as 290 K. (8)
