What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Pulse-width modulation (PWM) is the best conversion method to use for digitally-controlled variable DC voltage sources requiring high accuracy and resolution. Invented 50 years ago 1,2, the PWM ...

How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...
