An antenna with a temperature of 300 K is fed into a receiver with a total gain

Question:

An antenna with a temperature of 300° K is fed into a receiver with a total gain of 80 dB, T_e = 1500° K, and a bandwidth of 3 MHz.

(a) Find the available noise power at the output of the receiver.

(b) Find the necessary signal power P in dBm at the antenna terminals such that the output signal-to-noise ratio is 50 dB.
