comprising at least first and second comparators;
In a voltage discrimination device that applies a DC voltage to one input of each comparator and applies different reference voltages to the other input to discriminate the DC voltages using different threshold values, the output of the first comparator causes the output of the second comparator to 1. A voltage discriminator comprising: means for switching a reference voltage; said means causes a second comparator to have two threshold values.
