ABSTRACT:
A rotating member produces a signal corresponding to a given value M of angular rotation thereof. A clock produces pulses at a given rate. A counter mechanism is responsive to the signal and to the clock pulses for generating a number related to the number of clock pulses produced during a unit value X of rotation of the rotating member where X is unequal to M. The number may be used to determine when a value N of angular rotation has occurred.
