A short distance system is composed of two identical transmission lines with an amplifier between them. A 1 mW signal is transmitted at one end and is received at the other end with an SNR of 22 dB. Assuming a noiseless amplifier with a 10 dB gain and 2 dB of signal loss introduced by the transmission lines, then what was the input noise power at the transmitter end?
