摘要：Digital filtering is considered to be an important operation in reconstruction and visualization ofinformation, besides amounting to increase in computational efficiency. The Finite Impulse Responsebased digital filter bank is better responsive in respect of above specified advantages. In this paper, wepropose a novel approach in digital bandpass filter bank through Modified Kaiser window based Multiratetechnique as specified in (1)(2). A remarkable spectral output is achieved by way of increase in peakresponse, better selectivity, more stopband attenuation, better frequency response and computationalefficiency as compared to the existing methods(3)(4)(5). The simulation results are exhibited on account ofsatisfactory performance and comparison is drawn to verify the advantages in the proposed method. Thistype of filter bank is more suitable in typical hearing aid applications in order to arrive significant meritsfor improving quality of output.
