A novel signal quantization scheme based on adaptive differential pulse code modulation (ADPCM) is proposed and experimentally demonstrated. By adaptively adjusting the quantization step size using a ...

A project focused on sampling, pulse code modulation (PCM), and adaptive differential pulse code modulation (ADPCM) techniques using MATLAB. The implementation includes signal conversion and bit rate ...

A simple and effective solution is to use the pulse-width-modulation (PWM) output from a microprocessor to drive the load through a switched MOSFET.

Abstract: We propose a digital-cascaded-pulse-code-modulation radio-over-fiber (DCP-RoF) scheme and verify it experimentally in a coherent transmission system. The 50-Gbaud 2-order 6-bit DCP-RoF ...

VFD systems produce reflected waves, corona discharge, common mode current and electrical noise that overburden ordinary cables.

Many of the amino acids that make up proteins are encoded by genetic material in more than one way. An information theorist explains how principles of nature may account for this variance.

Pulse Width Modulation (PWM) is a technique used to control the intensity of a signal or digital output through the manipulation of its duty cycle. Initially developed for use in audio equipment, PWM ...
