The 555 timer IC is a handful of active components all baked into one beautifully useful 8 pin package. Originally designed for timing purposes, they became ubiquitous parts that can achieve almost ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Traditional PWM motor-control systems drive high-power bipolar transistors, which in turn perform the push-pull action through the three legs of the ac motor. Because there are three legs and 360° in ...
