Description: Matlab provides different options for digital filter design, which include function calls to
filter algorithms and a graphical user interface called Sptool. A variety of filter design
algorithms are available in Matlab for both IIR and FIR filters. This paper discusses the
different options in Matlab and gives examples of lowpass, highpass, and bandpass filter
designs. Platform: |
