AM transmitter develops a power output of (110 W) across a (70 2) 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.

Amplitude modulation

A radio signal can carry information in the form of sound or image for broadcasting or communication. For it to be sent to a greater distance, the signal must be changed or modulated in some way. One of the easiest way is to change the amplitude of the signal with variations of the video or the audio signal. This is called Amplitude Modulaton. In this modulation information of message is carried in amplitude of carrier signal.
