ABSTRACT:
Each output signal from a synchro device is applied to an individual voltage comparator through a step-down transformer. Each comparator is biased to a predetermined threshold level and produces an output signal whenever the magnitude of the associated synchro signal exceeds the threshold in the proper polarity. The comparator output voltages are applied to individual clocked flip-flops so as to produce binary output signals in a parallel format indicative of the rotor displacement of the synchro device.
