| Summary: | 碩士 === 國立臺灣大學 === 電信工程學研究所 === 94 === Owing to the increasing use of digital signal processing, the design of digital filters and filter banks plays an important role in this filed .In this thesis we present genetic algorithm and WLS algorithm with CORDIC algorithm for QMF banks and non-uniform division filter banks based on 1-D IIR all-pass filters with discrete coefficients .
The resulting two-channel QMF banks and non-uniform division filter banks can possess approximately linear phase response without magnitude distortion. The effectiveness of the proposed techniques is achieved by forming an appropriate Chebyshev approximation of a desired phase response .
In each chapter，we design some examples and the simulation examples are demonstrated and satisfy，
