Electronic filter projects and source code

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.

Joint bilateral filter in matlab

The following Matlab project contains the source code and Matlab examples used for joint bilateral filter. This function which is based on the bilateral filter provided Douglas R. Lanman, Brown University, September 2006, will compute the weights based on one image to be used as bilateral filter weights on another image.

A faster filter and filtfilt: speedup factor 2.5 to 25 in matlab

The following Matlab project contains the source code and Matlab examples used for a faster filter and filtfilt: speedup factor 2.5 to 25 . FilterM, FiltFiltM: Fast digital filter These functions are compatible to MATLAB's FILTER and FILTFILT commands, but they are faster (see screenshot):   FilterM: 30%-40% of FILTER runtime   FiltFiltM: 4%-20% of FILTFILT runtime ADDITIONAL FEATURES: - The dimension to operate on can be specified for FiltFiltM.

Two dimensional trilateral filter in matlab

The following Matlab project contains the source code and Matlab examples used for two dimensional trilateral filter. TRILATERALFILTER Two-dimensional trilateral filter. outputImage = trilateralFilter(inputImage,sigmaC,epsilon) filters the data in inputImage with the 2-D trilateral filter by P. Choudhury and J. Tumblin, http://www.cs.northwestern.edu/~jet/publications.html This implementation is a conversion of the OpenCV implementation by Tobi Vaudrey

Comb filter in matlab

The following Matlab project contains the source code and Matlab examples used for comb filter. Usage: [B,A] = COMB(order, scalar);             ORDER is the number of samples delayed prior to add             SCALAR is the coefficient that will be applied to                the delayed signal path at the final summation block.

Digital resistor capacitor (rc) filter in matlab

The following Matlab project contains the source code and Matlab examples used for digital resistor capacitor (rc) filter. Returns equivalent IIR coefficients for an analog RC filter Usage: [B,A] = RC_FILTER(r, c, fs, type);             R is the resistance value (in ohms)             C is the capacitance value (in farrads)             FS is the digital sample rate (in Hz)             type is a character string defining filter type                 Choices are: 'high' or 'low'
