DEVELOPMENT OF DIGITAL DATA TERMINAL AN/TYC-1

Abstract

Research continued on the development and construction of a rugged, highly reliable, fieldtransportable digital data receiver and transmitter. These equipments are to be used for transfer of data-processing information over military voice-communication channels and commercial voice channels. Basically the transmitter accepts eight parallel inputs at one of three Switch-Selectable character rates: 150, 75, or 37.5 characters per second. The transmitter converts the parallel inputs to a serial string of data (at 1200, 600, or 300 bits per second, respectively), and supplies a frequency-shifted data signal to the voice frequency channel. At the receiver, the frequency-shift signal is demodulated to a serial string of data pulses which is then converted to eight parallel outputs. The final output is eight parallel lines plus a timing signal. The AN/TYC-1 (XC-2) meets or exceeds the requirements of the equipment specification. (Author)
