delta modulation

[′del·tə ‚mäj·ə′lā·shən]
(electronics)
A pulse-modulation technique in which a continuous signal is converted into a binary pulse pattern, for transmission through low-quality channels.

delta modulation

A technique that is used to sample voice waves and convert them into digital code. Delta modulation typically samples the wave 32,000 times per second, but generates only one bit per sample. See PCM.
