Symbolic sensitivity analysis using nullators, norators and modified coates signal - flow graph

In the presented paper a method of determination of the first-order symbolic transfer function sensitivity is developed. It is based on the nullor equivalent presentation of linear networks. An important part of that method takes the use of modified Coates signal-flow graph (MCSFG) and the proposal of an effective way of easy obtaining a SFG representation of the nullor network given. An algorithm and a computer program ldquoHoneySenrdquo present first-order symbolic transfer function sensitivity. Using software the dependence of first-order transfer function sensitivity with respect to a parameter of a passive element is shown.
