碩士 === 國立臺灣大學 === 電信工程學研究所 === 88 === Recently, in consequence of wide use of digital signal processing day by day, ther are more and more researches concern about digital filter and digital filter bank, in the thesis , we focus on quadrature mirror filter banks(QMF banks) and non-uniform filter banks(NDF banks), a systematic algorithm is proposed to design them based on various criteria, among them, we use interior algorithm ( DAS Karmarkar’s algorithm) to make the process of optimization of entire designing more efficient , and performance of des- igning result as better as possible.
Secondly, we adopt FIR and IIR to design analysis filters, in the part of IIR designing, due to increase the problem of stability , so , we replace the denominator of filter with lattice structure, therefore, by controlling reflection coefficients to achieve stability of
system.
In this thesis , we mainly focus on L1 criteria to design filter banks, the formulated algorithm ,for each various criteria , proved by design examples to show the satisfactory result, after most, we identify feasibility of the proposed design methods.
