PWM

Electronic circuits can contain both analogue and digital components. PWM, which stands for Pulse Width Modulation, facilitates the control of analogue devices using a digital signal. Many electrical designs use PWM for regulation, with PWM used as a way to reduce the average power that is delivered by an electrical signal by chopping it up into smaller parts. RS offer a range of PWM Controller...
