1. A given FM transmitter is modulated with a single sinusoid. The output for no modulation is 200 watts into a 50 2 resistive load. The peak frequency deviation of the transmitter is carefully increased from zero until the second sideband amplitude in the output is zero. Under these conditions determine: (a) The average power at carrier frequency. (b) The average power in all the remaining sidebands. (c) The average power in the third – order sidebands.

1. A given FM transmitter is modulated with a single sinusoid. The output for no modulation is 200 watts into a 50 O resistive load. The peak frequency deviation of the transmitter is carefully increased from zero until the second sideband amplitude in the output is zero. Under these conditions determine: (a) The average power at carrier frequency. (b) The average power in all the remaining sidebands. (c) The average power in the third – order sidebands.
