ELECTRICAL POWER MEASUREMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrical power measurement apparatus which can reduce an arithmetic error which occurs at a multiplier and is not directly proportional to an input signal or an output signal. SOLUTION: The output signal of a correction signal generation section 108 which generates a correction signal in accordance with the input signal is added to the output signal of the multiplier 107 by an adder 110, thereby reducing the arithmetic error occurring in the multiplier 107.
