FIELD: pulse technique. SUBSTANCE: analog-to-digital converter has voltage-to-pulse-frequency changer, digital-to-analog converter, selector switch, electronic switch, reversing counter, control unit, AND and OR gates. Novelty is the introduction of pulse counter, two AND gates, OR gate, group of OR gates, and new design of control unit which eliminates conversion errors characteristic of prototype. EFFECT: improved conversion accuracy due to elimination of additional errors. 2 cl, 3 dwg
