Advanced continuous-time filter design in MATLAB
We present an original software for advanced continuous-time filter design. We have written this software in MATLAB as a toolbox which we call AFDESIGN. The AFDESIGN toolbox is based on original numerical procedures rooted in Jacobi elliptic functions. The AFDESIGN toolbox finds a comprehensive set of optimal designs to represent the infinite solution space. Quite opposite, conventional approaches and commercial software packages return only one design, thereby hiding a wealth of alternative filter designs that can be more robust when implemented in hardware. The AFDESIGN toolbox is easy to use, mouse driven, and user friendly to an unexperienced filter designer or practicing engineer.
