Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

In MIPI Soundwire: Digital Audio Simplified, we mentioned that digital audio formats including Pulse Code Modulation (PCM) and Pulse Density Modulation (PDM) are target applications for MIPI Soundwire ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

In PCM systems, distortion of very low level signals is known to occur, and in high-quality programme distribution it is the most objectionable signal degradation caused by this kind of system. This ...

A scientist whose research supported the development of modern computers and mobile phones has died aged 98. Professor Ken Cattermole, of East Bergholt in Suffolk, worked for many years at the ...
