ABSTRACT:
A polarity detector wherein voltage-to-current converters (21, 22) connected to transmission paths (1, 2) output currents according to potentials at the transmission paths (1, 2), respectively, and a current adder (23) adds the currents together. A current-to-voltage converter (24) converts the added current into the voltage (14). And comparators, whose offset voltage is less than 0 V (for example, -5 V) or more than 0 V (for example, 5 V) compare the output voltage (14) with a reference voltage to output signals indicative of whether the output voltage (14) is within a predetermined range, or more than the upper limit of the predetermined range, or less than the lower limit of the predetermined range. The polarity detector for discriminating the polarity of the plurality of transmission paths supplying signals and DC voltages is thus integrated, thereby reducing parts thereof.
