Abstract
In a device having a synchro resolver and a microprocessor, the apparatus of the present invention utilizes a pulse excitation technique for converting a synchro output signal to a digital format. A pulsed waveform is selectively applied to the input windings of synchro resolver and output voltages are induced in the output windings. A sample and hold circuit is selectively enabled and selectively coupled to the output windings of the synchro resolver, and the sampled output signal of the output windings is converted into a digital format via an analog-to-digital converter.
