~BSTR~CT OF THE DISCLOSURE Microprocessor controlled analoy-to-digital con- verting appa~atus. For each analog siynal input line there is a comparator having one inpuk connected to the associated analog signal input line. A ramp generator is connected in common to the other input o~ all o~ the comparators. A multipleY~ing arrangement is operated by the mic~oprocessor to couple a selected one of the comparators to a storage register in the microprocessor. The selected comparator compares -the voltage of the ana]og input signal to the ramp voltage. If the analog voltage is higher, the comparator ou-tput remains inactive and the microprocessor causes a count to be stored in the storage register. The ramp generator is toggled to increase the ramp voltage by a predetermined step. The comparison of the analog voltage and ramp voltage is repeated. If the comparator output remains inactive, another count is accumulated in the storage register and the ramp generator is toggled to increase its voltage by another step. The procedure continues until the ramp voltage exceeds the analog signal voltage and the compara- tor output becomes active. The microprocessor then causes the multiplexing arrangement to uncouple the selected comparator from the storage register. The accumulated count in the s-torage register is a digital representation o~ the analog signal voltage.
