ABSTRACT:
The circuitry illustrated utilizes duty cycle conversion means for providing signals indicative of Sin and Cos of an angle .theta. as well as the derivative of Sin.theta. and Cos.theta.. The derivative signals are then duty cycle multiplied by the Sin.theta. and Cos.theta. signals and the products are summed to provide an output d.theta./dt which is indicative of angular rate of change.
