AM
The modulated waveform consists of two parts: the carrier waveform and the
modulating waveform. In AM, the amplitude of the carrier waveform varies with
the instantaneous voltage of the modulating waveform. The parameters for the
AM are in Figure 2- 29

Term Explanation
Modulation Depth
The amplitude range (also called ‘Percentage Modulation’). Modulation depth
varies from 0% to 120%.
In the 0% modulation, the output amplitude is the half of the set one.
In the 100 modulation, the output amplitude is the same with the set
one.
