Abstract :
A three-level adaptive delta modulator for image encoding is presented. Its advantage is better tracking of signal levels. The characteristic constants of this modulator are designed to satisfy certain convergence and error properties. Behavioral curves of the modulator for different choices of the characteristic constants are included as well as the reconstructed versions of pictures that were encoded by this modulator.
