PWM waveforms are commonly used to control the speed of DC motors. The mark/space ratio of the digital wave-form can be defined either by using an adjustable analogue voltage level (in the case of a ...

A researcher in Russia thinks he has a way of generating power from wind turbines and other rotating devices that is super-efficient thanks to the elimination of any intervening power conversion ...

The behavior of analog circuits can often be characterized by sweeping their inputs with a signal going across a range of frequencies and then observing the output. These sweeps can be composed of ...
