Abstract
A step data to synchro converter for coupling one of a plurality of different step data transmitters to one of a plurality of different synchro receivers. The output of the step data transmitter is applied to an interface circuit and processed into a three bit binary code suitable for actuating a plurality of switching means. The switching means selectively apply an in-phase and an out-of-phase output of a transformer, which is responsive to the synchro receiver's reference voltage and frequency source, to a plurality of transformers associated with the input stator windings of the synchro receiver. The output of the plurality of transformers is a drive signal which satisfactorily approximates synchro data.
