The paper clarifies the difficulties occurring in definition of loop gain in linear networks. The cut-insertion theorem allows one to obtain the parameters of the feedback system resulting from insertion into a cut the two-port providing preservation of the currents and voltages in the rest of the network. Using this theorem for different cuts one can describe the same network by different feedback systems. The characteristic equation of these systems is invariant, yet their loop gains are… Expand

TLDR
It is shown that introducing the second additional transformer in cascade connection with the first one and doing the cut in the wire between the transformers one may reduce this method to the previously known Cut-Insertion Theorem (CIT) method. Expand

TLDR
The proposed cut-insertion theorem is based on the splitting of an arbitrary node into two nodes and on the insertion between them and another arbitrary ldquoreferencerdquo node, of a three-terminal circuit which keeps the network currents and voltages unchanged. Expand
