Abstract
A speed control circuit for a motor having a drive shaft which carries an optical encoder which generates pulses whose frequency is representative of the speed of the motor. The circuit includes a clock and a counter which generate a count between pulses, and a digital-to-analog converter (DAC) designed to receive each such count and to generate therefrom a corrective signal for maintaining the proper speed of the motor.
