ABSTRACT:
A synchro signal-to-digital signal converter for providing a digital signal representation of synchro angle value in response to sensed synchro signals representative of actual synchro stator voltage signals and actual synchro rotor voltage signals, includes an analog signal interface responsive to the sensed synchro signals for providing a digital signal representative of the ratio of the smaller of the difference signal magnitudes between each of two stator winding voltage signals and a third stator winding voltage signal selected as a reference, divided by the larger, and for providing discrete signal manifestations of the particular one of a plurality of successive ranges of synchro angle values associated with the sensed synchro signals received, the synchro to digital signal converter further including a signal processor responsive to the digital ratio signal and to the discrete signal manifestations of synchro angle range, for providing a signal representation of actual synchro angle value associated with the sensed synchro signal data received.
