Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Because of the widespread use of pulse-width modulation (PWM), the efficiency of a synchronous buck converter operating in this mode is well understood. However, relatively few designers understand ...

[Michael Kleinigger] posted a lengthy discussion on Pulse-Width Modulation that goes beyond the traditional beginner tutorial. He starts a bit of background info on PWM and a tip about using a camera ...

Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...
