The Two Extra Element Theorem

By Dr. R. D. Middlebrook - January 04, 2022


The Two Extra Element theorem (2EET), a logical extension of the single EET, enables a transfer function to be assembled, essentially in final form, from separate calculations on a circuit model that is simpler by the absence of two elements.  The 2EET provides not only a potentially shorter, simpler, and easier analysis method, but also contributes a Low-Entropy Expression in which the ordering and grouping of terms contains useful design-oriented information.  As an example, the 2EET is employed in design-oriented analysis of a bridged-T filter.
