A PWM, or pulse width modulation signal is used to reduce the electrical power supplied to an electrical device by switching the signal on and off at a high frequency. The signal thus produced will have a train of pulses, and Electrical motors used in mobile robots are controlled by modifying the voltage applied to the motors using a technique called pulse width modulation. Pulse Width Modulation is also known as pulse duration modulation (PDM). Here, as the name suggests, the width of the pulse is varied in proportional to the amplitude of the signal. Since the width is changing, the power loss can be reduced when compared to PAM signals. From the figure, it is clear that the amplitude of the signal is constant.
