Analog transmission

Japanese: アナログ伝送 - アナログでんそう(英語表記)analogue transmission
Analog transmission
An electrical signal whose amplitude changes continuously over time, such as an audio signal or a television signal, is called an analog signal. In contrast, a digital signal is a signal that is sampled at regular time intervals, the sampled values ​​quantized, and represented as a discrete numerical sequence. Data, for example, can itself be considered a digital signal. Analog signals are converted into digital signals by analog-digital converters, and conversely, converted back into analog signals by digital-analog converters.

Japanese:
音声信号やテレビジョン信号のように,時間に対してその振幅が連続的に変化する電気信号をアナログ信号という。これに対して,アナログ信号を一定時間間隔で標本化し,その標本値を量子化して,離散的な数値系列として表した信号をディジタル信号という。データなどは,それ自体ディジタル信号と考えられる。アナログ信号は,アナログ‐ディジタル変換器によってディジタル信号に変換され,逆に,ディジタル‐アナログ変換器によってアナログ信号に戻される。
