# Critical analysis of cut-insertion theorem

@article{Filanovsky2012CriticalAO, title={Critical analysis of cut-insertion theorem}, author={I. Filanovsky}, journal={2012 IEEE 55th International Midwest Symposium on Circuits and Systems (MWSCAS)}, year={2012}, pages={658-661} }

The paper gives a critical analysis of recently proposed cut-insertion theorem. It is shown that all cut-insertion equivalent networks can be obtained using a simple extension of the substitution theorem. For example, using two voltage sources connected in parallel between a chosen and reference node, then cutting the wire between the voltage sources one concludes that a wire with a known voltage and known current can be substituted by a two port where one input is connected to the impedance… Expand

The paper shows how to circumvent this difficulty: using the cut-inserted two-port which includes an independent current (voltage) source on one side of the cut and an independent voltage source on the other side one obtains the signal graph of the feedback system of order two. Expand
