Abstract :
In the proposed approach, the number of parameters to be optimized are reduced significantly, thereby leading to a faster design of the two-channel QMF banks. The characteristics of the filters obtained are comparable to those of some of the existing QMF banks, in terms of the overall amplitude distortion and the minimum stopband attenuation
