ABSTRACT:
An electronic circuit having control data registers (24-28) for receiving the output of a digital counter (20) that records clock pulses within a measured time that is determined by a rotary speed sensor (14) which produces a square wave pulse train signal and separate registers (30,32) for recording the time of each signal developed by the speed sensor and the time to produce a pulse train signal of predetermined length whereby the data in the data registers may be used to determine velocity and derivatives of that velocity for use in solving dynamic equations stored in memory thus effecting control system output functions.
