STAIRCASE VOLTAGE GENERATOR

摘要

Remote control signals actuate digital circuitry suitable for controlling the volume of an audio amplifier. A digital counter either increases or decreases in count corresponding to a desired volume control level. Circuitry associated with the counter causes an audio amplifier control voltage derived therefrom to increase at a first rate of change in response to a predetermined range of counter output and at a second rate of change corresponding to a second predetermined range of counter output.
