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 ...

Fig.1: NRZ signal (top) and eye diagram (bottom). Pulse amplitude modulation builds upon this concept by encoding data across multiple voltage levels. PAM4 uses four levels. A PAM4 signal can appear ...

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.
