Multiplexed-demultiplexed synchro demodulation apparatus |
摘要 |
The outputs of a three-wire synchro are applied to a multiplexer which provides the multiplexed synchro outputs to an amplifier and demodulator. The demodulated synchro outputs are applied to a demultiplexer whose outputs are filtered to provide demodulated d.c. voltages corresponding to the synchro output signals. The demodulated d.c. voltages are applied to a conversion circuit for providing the sine and cosine of the angular position of the three-wire synchro device. The multiplexer, demultiplexer and demodulator are synchronized by the synchro a.c. reference signal.
