Title:
波形復元装置及び波形復元方法
Document Type and Number:
Japanese Patent JP6712071
Kind Code:
B2
Abstract:
The present invention is configured so as to comprise: a high-pass filter (2) that eliminates an offset included in an AC signal Vin input from a signal input terminal (1); and a waveform restoration unit (3) that, using a time constant τ of the high-pass filter (2), restores the waveform of the AC signal Vin prior to being input to the high-pass filter (2), such restoration being from an AC signal Vout in which the offset was eliminated by the high-pass filter (2). Due to this configuration, the waveform distortion of the AC signal Vout, which is distorted by the elimination of the offset by the high-pass filter (2), is compensated. As a result, the waveform of the AC signal Vin prior to being input to the high-pass filter (2) can be restored after elimination of the offset included in the AC signal Vin.
