The signal to noise ratio at the receiver is required to be at least 17 dB. The average noise power at the receiver is 1 mW. The cable loss between the transmitter and the receiver is 2.5 dB/km and there is 55 km of cable between the transmitter and the receiver. There is a 25 dB amplifier between the transmitter and receiver. Determine the transmit power at the transmitter to achieve a signal to noise ratio of 17 dB at the receiver?© BrainMass Inc. brainmass.com March 4, 2021, 11:33 pm ad1c9bdddf
