ABSTRACT:
An adaptive delta modulation circuit having an analog adaptation circuit and an integrator circuit. The adaptation circuit exponentially converts a voltage which is proportional to the average of a time duration of an overload control signal to an adaptation current which is averaged and converted to an adaptation voltage. An integrator circuit includes a sole switch which shorts to ground a circuit point for generating an analog signal formed of line segments; each segment has a slope magnitude controllable by the adaptation voltage.
