In signal processing, the Kautz filter, named after William H. Kautz, is a fixed-pole traversal filter, published in 1954.〔 〕〔 〕 Like Laguerre filters, Kautz filters can be implemented using a cascade of all-pass filters, with a one-pole lowpass filter at each tap between the all-pass sections. == Orthogonal set == Given a set of real poles , the Laplace transform of the Kautz orthonormal basis is defined as the product of a one-pole lowpass factor with an increasing-order allpass factor: : : :. In the time domain, this is equivalent to :, where ''ani'' are the coefficients of the partial fraction expansion as, : For discrete-time Kautz filters, the same formulas are used, with ''z'' in place of ''s''.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Kautz filter」の詳細全文を読む スポンサード リンク
