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 ...

アナログ：音声などのように連続する情報。 デジタル：連続するアナログ情報を細かく区切って「0」「1」に置き換えた不連続的な情報。 PCM Pulse Code Modulationは、アナログ信号をデジタル信号に変換する方式の一つ。 ①信号の標本化（サンプリング ...

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 ...

Equipment is described which has been constructed for converting analogue television signals into 8-bit PCM signals and vice versa. The conversion rate used for video signals is approximately 13 ...

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 ...
