Design of Multi–Channel Non–Uniform Filter Bank

Jyotsna Ogale, Alok Jain

Abstract :

In this paper an improved and simplified approach is presented for designing multi-channel cosine modulated non-uniform filter bank. The method employs Blackman window family to design prototype filter. The amplitude distortion function, which is used as an objective function, is minimized by optimizing the cutoff frequency of the prototype filter. The results show significant reduction in amplitude distortion with improvement in stop band attenuation characteristics compared to earlier reported work.
