A tool for generating one or several transfer functions for a given system. Applicable for both continuous- and discrete-time systems. System can also be purely symbolic.
This is a tool for generating transfer function information with ease. It is based on a nodelist presentation of a system which makes the exploring of the transfer function information less prone for errors.
The tool reads a user-defined textual nodelist which defines the signal flow graph of a system and then generates the needed transfer function(s).
The tool is generic so that it is easily applicable for many purposes. Tool can be applied to digital filter design, circuit design, delta-sigma modulator analysis or even reflection analysis s-parameter measurements in RF techniques and in optics.
The package includes 10 examples of nodelist files and some of them are presented in the manual. It also includes a useful extension: a parameter solving tool for e.g. filter design.
Requires Matlab 6 or higher and optionally control system toolbox (the tool has an optional output for an LTI-model).
