[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

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 ...

The waveform demonstrates the results from the two tests conducted on the optical modulator: on-off-keying method (top) and four-level pulse-amplitude-modulation method (bottom).

This paper describes a generalized method to achieve Direct Waveform Synthesis (DWS) for different modulation formats both binary and multi-level, in order to include this mechanism in the general ...

The APB PWM Module is a standard APB peripheral that generates a programmable duty cycle output signal. The frequency of the output waveform is either PCLK/256 or PCLK/4096, depending on whether a ...
