Abstract
An adaptive delta modulator for television signals has been implemented in which the step magnitude depends on the four most recent sign bits. Overshoot limits the largest step size that can be used: to overcome this limitation an overshoot suppression scheme has been devised, considerably improving picture quality. An adaptive 2-bit differential pulse-code modulation (DPCM) system is also described.
