Abstract

PURPOSE: To reduce the numbers of latch circuits, AND gates, OR gates, etc., to half by supplying level outputs equal in absolute value to one OR circuit according to the output of a comparator.
CONSTITUTION: Of the circuit which consists of resistances 23, 24, 25 and 26 connected in series and develops several reference voltages, the positive reference potential terminal is connected to the negative terminals of comparators 20 and the negative reference potential terminal to the positive terminals of comparators 20. Outputs, equal in abosolute value, of comparators 20 connected so as to apply analog input signals for coding are supplied to one OR circuit 21, whose output is connected to latch circuit 22. To the output of circuit 22, AND gate 27 is connected so as to generate an output of [1] only at the switching part. Circuit 22 reads and holds the output of OR logic and that of polarity decision comparator 20 (8) by clocks.
