An engaging filter bank structure with a simplified style, being supported one example filter is that the Cosine-Modulated Filter Bank (CMFB). Recent advances have greatly reduced its procedure value by using Interpolated Finite Impulse Response (IFIR) and Frequency Response Masking (FRM) approach to style the example filter. The current paper, discusses the utilization of rounding error and sharpening over typical approach to style CMFBs. It's verified that by applying totally different rounding error factors, requiring minimum to most range of multipliers and stuck sharpening polynomials, the strategy will cut back the procedure complexness and improves the performance of ensuing FBs.
