…Figure 2 shows the operating waveforms of each part. Since y ( t ) increases and decreases by a fixed amount ⊿ (delta), it is called delta modulation or constant-difference modulation. In practice, adaptive delta modulation, which makes ⊿ variable to improve operating characteristics, has been put into practical use and is widely used for satellite communications, mobile radio, military, etc. [Kaneko Hisashi]. … *Some of the terminology that refers to "adaptive delta modulation" is listed below.

…図2は各部動作波形であり,y(t)が一定量⊿(デルタ)ずつ増減するため,デルタ変調または定差変調と呼ばれる。実際には,動作特性向上のために⊿を可変にしたアダプティブデルタ変調が実用化されており,衛星通信用,移動無線用,軍用などに広く用いられている。【金子 尚志】。… ※「アダプティブデルタ変調」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
