This research aims to design and implement of tree-structured multichannel filter banks using MATLAB. The multichannel filter banks analysis are evaluated by the Digital Signal Processing (DSP) techniques. The multi rate analysis is suitable for sampling rate reduction and sampling rate increase on the digital filter design. When increasing sampling rate, filtering follows the up-sampling operation. The role of the filter is to attenuate unwanted periodic spectra which appear in the new baseband. The performance evaluation for tree-structured multichannel filter banks design is described in this research work. The experimental results for implemented design are implemented in this paper. The use of an appropriate filter enables one to convert a digital signal of a specified sampling rate into another signal with a target sampling rate without destroying the signal components of interest. The performance of multirate filtering for implemented design is evaluated by using MATLAB.
