DIGITAL FILTER, AUDIO SIGNAL PROCESSING SYSTEM, AND METHOD OF DESIGNING DIGITAL FILTER

摘要

A digital filter, an audio signal processing system, and a method of designing a digital filter are provided, where the digital filter reduces a DC component of a signal which corresponds to an input data sequence, and has a transfer function H(s) represented as; ;where a cutoff frequency F0 is ω0/2π and a Q factor is Q.
