An antenna with average noise temperature 60 K connects to a receiver through various microwave elements that can be modeled as an impedance matched attenuator with an overall loss of 2.4 dB and a physical temperatures of 275 K. The overall system noise temperature of the receiver Tsys 820 K.
If receiver has an available power gain of 110 dB and a noise bandwidth of 10 MHz, the available output noise power of receiver is??
