摘要： PROBLEM TO BE SOLVED: To provide a noise removing device capable of removing impulse magnetic noise without losing real time property.SOLUTION: The noise removing device includes: an estimated value calculation section 13 operating in synchronization with the occurrence of impulse magnetic noise; and a window function calculation section 14 calculating a window function coefficient value. By multiplying the estimated value calculation section 13 by the window function calculation section 14, a noise estimation interpolation signal is calculated and, by deducting the noise estimation interpolation signal from an input signal 11, the impulse magnetic noise is removed.
