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 ...
AVアンプを調べていると、通信モードが「PCM」になっていることがわかった。 PCMとは「Pulse Code Modulation」の略で、出力がデジタル5.1chの音源でもTVモニタを通すとPCM.2chまでダウンミックスされてしまうらしい。 PCMがダメというわけではない。ニンテンドー ...
The various methods for converting analogue signals into the form of pulse-code modulation and back again are reviewed. Reasons are given for preferring a particular method of conversion called ...
A North American telephony standard for converting analog voice into a digital data stream using pulse code modulation (PCM). The "pulse code" in PCM comes from the telephone company's method of ...
Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...
