Symbolic computation of digital filter transfer function using MATLAB
We present an original software DFSYM for symbolic computation of transfer function of digital filters and linear time-invariant discrete-time Systems. The software uses standard MATLAB commands and MATLAB SYMBOLIC TOOLBOX. The transfer function is derived directly from the filter schematic created by DrawFilt. DFSYM finds transfer function of filters with arbitrary real or complex coefficients. Filter designers, practitioners, students, researchers, educators and scientists can use DFSYM to evaluate, validate, document or verify the existing filter realizations or to explore, get insight to and optimize the filters they work on.
