曲線位相フィルタによる信号のスペクトルの抽出法

Description

By using curved phase characteristic the group delay response is not able to have a Flat but a big slope. On condition that the group delay response respond to the frequency one on one, the output is like the light spectrum that form smoothly from a high frequency to a low frequency. In case of using bandpass filter the output is limited within the frequency of a passband, but in this place the using filter is allpass filter. Specially though the wave that passed through the allpass filter is what we call "a distortion wave", by means of repeating this many times, the output wave come to form like the light spectrum.
