A system for digitizing and interfacing analog data from a plurality of amplitude modulated periodic signals with a computer in which an alternating reference signal is identified and sampled input data to be digitized is synchronized at the same time reference point of the waveform of the reference signal. Pulses from a real time clock are counted and synchronized with the reference signal and this synchronized signal is delayed and fed to a timing circuit which starts the multiplexing of the input signals and also activates an address counter to initialize the address locations in the computer. The analog data from the multiplexer is converted to digital values by an analog-to-digital converter and fed to the computer at the given address.
