Abstract:
A control section 8 detects the symmetry of an input pulse-like noise waveform with respect to a reference value from its Fourier spectrum distribution, and restricts, in the case of a symmetric wave, the operation of a noise elimination circuit such as a noise killer circuit 7, which performs previous value hold or various interpolation processing.
