ABSTRACT:
Method and apparatus for producing a speed-proportional signal from first and second transmitter voltages which are produced by an incremental position generator and shifted 90.degree. with respect to each other in directions which correspond to the direction of rotation of the incremental position generator. An adder and a subtractor are provided for respectively producing a sum signal corresponding to an addition of the transmitter voltages, and a difference signal corresponding to the difference between the transmitter voltages. The sum and difference signals are each differentiated over ranges which correspond to .+-.45.degree. about their respective zero crossing. The differentiated signals are rectified in a controlled manner responsive to the phase of the first and second transmitter voltages. In this manner, a speed-proportional voltage is produced having a polarity which corresponds to the direction of rotation of the position transmitter.
