ABSTRACT:
A data handling system receives analogue signals on a number of input lines by scanning the lines continually. The input signals are set into a register and after each scan their positions shifted by one place. A/D converters produce digital signals from these and a computer compares the digital signals with stored threshold data to yield a status binary 1 or 0 according to whether the inputs are inside or outside the threshold. Test signals are interleaved with the analogue signals. The status signals are assembled in a register and continuously recycled so that a constant stuck at 1 or stuck at O defect is at once recognized. The input lines are replicated and a majority vote is taken before any actuator is exercised.
