Extra Credit This problem is optional. It can increase but cannot decrease your grade. Work Problem 3 again but use the thermal noise power at the receiver input if the receiver bandwidth is 200 kHz and its temperature is 300 Kelvin. Problem 3 (6 points) The ballpark's PA system receives audio from an FM broadcast receiver so that the baseball fans can hear music as they arrive to see the ballgame. A simple antenna delivers a -100 dBm signal to a long coaxial cable that sends the signal to the FM receiver. The coaxial cable and the connectors on both ends have a total loss of 12 dB at the FM station's 100 MHz radio frequency. What signal power in dBm is delivered to the FM receiver? The thermal noise power at the receiver input is -150 dBW. What is the noise power in dBm? What is the signal-to-noise ratio (SNR) in dB at the receiver input? What will be the SNR in dB if the antenna gain is increased by 6 dB? Extra Credit This problem is optional. It can increase but cannot decrease your grade.
