Finding the Sensitivity to Transfer Branch by Graphs

The actual question in the area of circuit analysis and synthesis methods is the problem of sensitivity determination. The proposed approaches for sensitivity calculation are directed to the obtaining of a symbolic form and to avoiding the direct differentiation by using a signal-flow graph. Interesting results in this topic are based on Mason's graphs, and Coates' graphs. This paper presents the comparison of some methods to finding the sensitivity to transfer branch: previously published algebraic method and proposed SFG method.
