Hybrid filter banks with fractional delays minimax design and applications to multichannel sampling in matlab

The following Matlab project contains the source code and Matlab examples used for hybrid filter banks with fractional delays minimax design and applications to multichannel sampling. MATLAB Implementation and demo to design of filters in a hybrid FB with fractional delays.

Filter bank design in matlab

The following Matlab project contains the source code and Matlab examples used for filter bank design. The goal is to design M analysis and synthesis FIR filters so that the analysis filters satisfy some frequency specifications and the filter bank(almost) meets the perfect reconstruction (PR) conditions.

Generates a mel filter bank for a given frequency vector in matlab

The following Matlab project contains the source code and Matlab examples used for generates a mel filter bank for a given frequency vector . % melfilter Create a mel frequency filterbank % % [Filter,MelFrequencyVector] = melfilter(N,FrequencyVector,hWindow) % % Generates a filter bank matrix with N lineary spaced filter banks, % in the Mel frequency domain, that are overlapped by 50%.

Compute n x n dft matrix in matlab

The following Matlab project contains the source code and Matlab examples used for compute n x n dft matrix. % dftmat = DFT matrix of order N x N; % N = Order of the matrix % computes the DFT matrix of orer N x N; % DFT matrix is a n x n matrix defined as Wn=[(Wn)^km] % Wn=exp(-j*2*pi/n) %Reference: Multirate Systems and Filter banks by P.
