What is it? -A fully automated flowgraph (signal flow graph) analysis tool using Matlab’s symbolic and control system toolbox. -A tool for generating one or several transfer functions for a given control system. -An analysis tool for both continuous- and discrete-time control systems. -Includes a parameter solving tool Introduction From a simple textual nodelist model the user can easily generate one or several transfer functions between any nodes and apply the result to control system analysis. Such a versatile tool can be applied to filter design, delta-sigma modulator analysis or even reflection analysis s-parameter measurements in RF techniques and in optics. Some design examples are attached to the package and also presented in the manual. Instructions -Unpack ZIP-file and extract the file examples.tar in the same directory. -Read the manual. -Study the demo (flowdemo.m) -See what's in the *.flw files. -See help for flow_tf.m. -Output transfer function(s) are struct arrays, so typing e.g. H.sym{1} shows the result (see the demo). Contents -m-files (*.m): flow_tf: the flowgraph analysis function find_params: parameter solver flowdemo: a demo script test_all_nodelists: runs all *.flw files in the package -textual nodelist files (in examples.tar): zpar a terminated z-parameter two-port circuit model biquad: biquad filter example IIR: IIR filter example integra: a simple integrator efb: error-feedback delta sigma MOD1: 1st order delta sigma MODL: Lth order pure differentiation delta sigma CRFBSYM: 3rd order symbolic delta-sigma CRFBNUM: 3rd order numeric delta-sigma fiori 3rd order efb delta-sigma.
