AM transmitter develops a power output of (110 W) across a (702) resistive load
when a sinusoidal test tone with a peak amplitude of (4 V) is applied to the input of
the modulator it is found that the power output increases by 50% of unmodulated
power output under these conditions determine:
1- The average power output in each sideband.
2- Modulation index.
3- The peak amplitude of the modulated waveform.
4- The total average power in the output if the amplitude of the modulating sinusoid
is reduced to 3 V.
