Abstract:
A device for converting multi-channel, analog synchro transmitter output signals to digital format comprising:a data bus;a plurality of synchro-to-digital conversion channels having outputs connected to the data bus;a digital-to-synchro converter having an input connected to the data bus, and responsive to predetermined bits on the data bus, and having an analog output in the form of a synthesized analog synchro transmitter output; andswitching means, responsive to other predetermined bits on the data bus, for alternatively connecting each synchro-to-digital conversion channel either to the output of a synchro transmitter or to said analog output of the digital-to-synchro converter;whereby, for testing, the synthesized analog output of the digital-to-synchro converter can be substituted for synchro signals in selected conversion channels, with the selection of conversion channels and the magnitudes of the synthesized analog synchro signals both under the control of data on the data bus.
