Q7: A given FM transmitter is modulated with a single sinusoid. The output for no modulation is 200 watt into a 50 Q 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 the peak amplitude of: (a) The total waveform. (b) The upper first – order sideband. Ans: (a) 141.42 v (b) -43.37 v.
