ABSTRACT:
An analog-digital converter designed to provide digital data by converting analog input voltage signals into pulse signals by a voltage-frequency converter, and counting said pulse signals by a counter, the improvement being that the A-D converter comprises a sequence controller which selectively supplies low-level or high-level input voltage signals to the A-D converter before analog input signals being measured are received therein.
