WebSep 18, 2024 · PWM describes the basic technique for generating a rectangular pulse wave with modulated pulse width resulting in the variation of the average value of the waveform. A PWM waveform can be categorized by 2 parameters: waveform period (T) and duty cycle. WebJun 16, 2024 · Pulse Width Modulation (PWM) is a digital technology that uses the amount of power delivered to a device that can be changed. It generates analogue signals by using a digital source. A PWM signal is basically a square wave which is switched between on and off state. The duty cycle and frequency of a PWM signal determine its behaviour.
