Paper Title - An Optimized Design Of Uniform-Band And Octave-Band Filter Bank Using Variable Window Function


Abstract
In this paper tree-structure approach is used for designing uniform-band and octave-band filter bank (FBs). In tree-structure approach normally perfect-reconstruction (PR) is used but PR is not always feasible due to some limitations. Therefore in this proposed work filter banks are designed with NPR by allowing small amount of distortion at the output. A single variable linear optimization is used to minimize the amplitude distortion. The prototype filter designing become more efficient by the windowing technique. The variable window functions are used for windowing. In this way filter banks are design with high efficiency. Further, several design examples are included to show improved performance of designed FBs over existing methods. Keywords- Tree-Structure; Filter Bank; Uniform-Band; Octave-Band; Optimization.
