However, generating Matlab code from the filter-designer app itself does not yield these coefficients as function-returns. I also asked remez to work harder by increasing maxiter. 4 FIR Filter Design By MATLAB FDA Tool Filter Design and Analysis Toolbox in MATLAB is a very powerful but user-friendly GUI lter designer which can be used. Using the Matlab filter-designer results in direct-form II transposed coefficients, which i need. I relaxed the transition bandwidth to 2 Hz and increased the order to 300. I gave it a shot with the bandwidth you need (20 Hz). You may need to try a few combinations before you get a filter you like. ![]() The degrees of freedom you have available are: filter bandwidth, filter order, and transistion bandwidth.
