ABSTRACT:
Apparatus for transmitting particular output signals from a plurality of analog-to-digital converters to the guidance computer of an inertial navigation system. The number of channels of signals to be transmitted exceeds the number of available data lines. The A/D converter output is converted, according to its particular logic code, to a series of pulse counts which are thereafter multiplexed in a pulse combiner and applied to the data lines. During a first selected time interval, the pulses are accumulated for interleaving and transmission with the real time pulses in a second selected time interval. The multiplexing combines such interleaved pulses from one A/D converter output with those from another such output in alternate time intervals. Sync words are transmitted along with the data to permit the guidance computer software to demultiplex the data.
