ABSTRACT:
The invention relates to a control circuit for controlling the speed ratio of a lead motor and a follower motor. The outputs of pulse generators driven by the motors are compared by being fed the positive and negative inputs of a bidirectional counter which outputs a positive or negative value indicative of the sensed speed ratio. A digital/analog converter driven by the counter effectively controls the speed of the follower motor pursuant to the sensed speed ratio.
