A satellite telemetry link operating in S-band uses frequency modulation to transmit the value of an analog voltage on the satellite to a receiving Earth station. The voltage has a range from -1.0 volts to +1.0 volts, and a maximum frequency of 1000Hz.The FM modulator on the satellite has a constant of 10,000 Hz per volt. At the receiving Earth station the C/N ratio of the signal is 10 dB measured in the Carson’s rule bandwidth, and is 3 dB above the FM threshold of the FM demodulator.
a. What is the Carson’s rule bandwidth for the FM signal?
b. What is the baseband S/N ratio at the Earth station receiver output for the recovered analog signal?
