Abstract

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.

数字滤波器传递函数的MATLAB符号计算

本文提出了一种用于数字滤波器和线性时不变离散系统传递函数符号计算的独创软件DFSYM。该软件使用标准的MATLAB命令和MATLAB符号工具箱。传递函数直接从DrawFilt创建的滤波器原理图中导出。DFSYM求任意实系数或复系数滤波器的传递函数。过滤器设计师、从业者、学生、研究人员、教育工作者和科学家可以使用DFSYM来评估、验证、记录或验证现有的过滤器实现，或者探索、深入了解和优化他们所使用的过滤器。
