On July 14, MP3 audio data reduction will be a quarter of a century old – A success story from Germany that is far from over.

A more advanced digital electronic system converted each voice signal into digital by using Pulse Code Modulation (PCM).

An experiment in transmitting speech by Pulse Code Modulation, or PCM, is described in this paper. Each sample amplitude of a pulse amplitude modulation or PAM signal is transmitted by a code group of ...

As a result, three typical optimized triangular pulse–current waveforms were obtained under three distinct conditions. Finally, based on multi-module cascading and the principles of programmable TMS ...

CRISPR construct to genetically ablate the GABA transporter GAT3 in the mouse visual cortex, with effects on population-level neuronal activity. This work is important, as it sheds light on how GAT3 ...

A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ...

IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity.

Predictive genetic circuit design for phenotype reprogramming in plants The predictive design of gene circuits in plants has been challenging and lagging behind other organisms.

Finally, we terminate Block-based Differential Pulse-Code Modulation (BDPCM) early and then select the best transform type in Intra mode prediction to improve coding speed. Experimental results ...
