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: |

Description: Filter can be FIR or IIR.
- Filter type can be lowpass, highpass, bandpass, or bandstop.
- Direct methods or optimization ones can be used during the design procedure.
In order to learn how you can use this toolbox, please copy all the codes included in the "Dig_Filter" folder into the current directory of your Matlab and type "help Dig_Filter".
Note 1:
At the moment, because of copyright issues, I removed bfgs , dfp , and inex_lsearch optimization algorithms. So, in the case of designing IIR filters using optimization algorithm, Optimization_Method in the toolbox just can work via fminunc which is a Matlab function.
IMPORTANT NOTE:
In the case of designing IIR filters using optimization methods, Dig_Filter uses MATLAB functions bfgs, dfp, and inex_lsearch. These functions are part of the MATLAB support materials of the following textbook:
A. Antoniou and W.-S. Lu, "Practical Optimization: Algorithms and
Applications", Springer, 2007-Filter can be FIR or IIR.
- Filter type can be lowpass, highpass, bandpass, or bandstop.
- Direct methods or optimization ones can be used during the design procedure.
