Filter Designer enables you to quickly design digital FIR or IIR filters by setting filter performance specifications, by importing filters from your MATLAB® workspace or by adding, moving, or deleting poles and zeros. Filter Implementation Once you have designed your filter using filter designer, the block automatically realizes the filter using the filter structure you specify. Filter Designer is a powerful graphical user interface (GUI) in Signal Processing Toolbox for designing and analyzing filters. % Generated by MATLAB(R) 9.10 and Signal Processing Toolbox 8.6. Filter designer provides extensive filter design parameters and analysis tools such as pole-zero and impulse response plots. %GEN_IIR_OSIX_BP Returns a discrete-time filter object. Generated code: function Hd = gen_iir_osix_bp(Fc1, Fc2, Fs)
