delta modulation
δ［增量］调制
Conversion of an analog signal, such as voice, to a digital format in which the amplitude difference between successive samples of the analog signal is represented by a set of digits coded to express the quantized amplitude difference. In its simplest form, the quantized magnitude of the amplitude difference can have only one value other than zero.
一种将模拟信号,例如声音,转换成数字信号的方法,其中将两次连续抽样的模拟信号的幅 度差用一组数字编码来表示。它的最简单的形式为:幅度差数值仅有一个除零以外的值。 |
