PWM-based PPM format for dimming control in visible light communication system [PDF]
We report simulation results of pulse width modulation (PWM)-based pulse position modulation (PPM) signal format for visible light communication systems. For simultaneous operation of data transmission and dimming control, PPM data format is added to PWM

Comparison of single- and double-sided pulse width modulated signals with non-linear predistortion [PDF]
Class D amplifiers are based on a low-bit pulse width modulated (PWM) signal reconstructed through the lowpass characteristic of the loudspeaker. To create a PWM signal, a non-linear conversion from a standard pulse code modulated (PCM) signal has to be ...

Spectral characterisation of shortened pulse position modulation format [PDF]
Shortened pulse position modulation (SPPM) is a new modulation format that has recently been proposed for underwater wireless optical communications. A full spectral characterisation of SPPM is considered and original expressions are presented, which ...

Spectral characterisation of nk pulse position modulation format [PDF]
nk pulse position modulation (PPM) is a new modulation format that has recently been proposed for the optical wireless channel. This Letter considers, for the first time, a full spectral characterisation of -PPM and presents original expressions, which

Improvement of Pulse-Width Modulation Algorithm for Thermal Plant Control [PDF]
The results of the pulse-width modulation algorithms analysis are presented in the paper. The following two algorithms are analyzed: pulse-width modulator (PWM) based on the sawtooth waveform generator and PWM based on an integrator and a switch element.

Phase accumulated carrier pulse width modulation [PDF]
An alternative approach to digital PWM generation uses an accumulator rather than a counter to generate the carrier. This offers several advantages.
