7.  Measurement of Loop Gain in Feedback Systems
   Intl. J. of Electronics, 38, 485—512, Apr. 1975.
   In the design of a feedback system it is desirable to make experimental measurements of the loop gain as a function of frequency to ensure that the physical system operates as analytically predicted or, if not, to supply information upon which a design correction can be based. In high loop-gain systems, it is desirable that the loop-gain measurement be made without opening the loop.
   This paper discusses practical methods of measuring and interpreting the results for the loop gain of the closed-loop system by a voltage-injection or a current-injection technique: extension to the case in which the measurement can be made even though the system is unstable; and extension to the case in which neither the voltage- nor current-injection technique alone is adequate, but in which a combination of both permits the true loop gain to be derived.
   These techniques have been found useful not only in linear feedback systems but also in describing-function analysis of switching-mode converters and regulators.

11. Null Double Injection and the Extra Element Theorem
    IEEE Trans. on Education, 32, No. 3, August 1989.
    The extra element theorem (EET) states that any transfer function of a linear system can be expressed in terms of its value when a given "extra" element is absent, and a correction factor involving the extra element and two driving point impedances seen by the element.
    
    One class of applications is when a system has already been analyzed and later an extra element is to be added to the model: the EET avoids the analysis having to be restarted from scratch. Another class of applications is when a system is to be analyzed for the first time: if one element is designated as "extra", the analysis can be performed on the simpler model in the absence of the designated element, and the result modified by the EET correction factor upon restoration of the "extra" element.
    
    Although the EET itself is not new, its interpretation and application appear to be little known. In this paper, the EET is derived and applied to several examples in a manner that has been developed and refined in the classroom over a number of years. The concept of "null double injection" is introduced first, because it is the key to making easy the calculation of the two driving point impedances needed for the EET correction factor.

12.  Low-Entropy Expressions: the Key to Design-Oriented Analysis
    Proc. IEEE Frontiers in Education, 21st Annual Conf., Purdue Univ., Sept. 21—24, 1991; 399—403.
    The perception of many electronics design engineers is that they are able to apply few of the formal analysis methods they have been taught, and are largely unprepared for the realization that Design is the Reverse of Analysis.
    Suggested here is a different perspective for teaching, based on the premise that only analysis that is design-oriented is worth doing, and that results should be presented in Low-Entropy Expressions. High- and Low-Entropy Expressions are described. A simple analog circuit example illustrates one Method of Design-Oriented Analysis: Doing the Algebra on the Circuit Diagram.

13. The Two Extra Element Theorem
    Proc. IEEE Frontiers in Education, 21st Annual Conf., Purdue Univ., Sept. 21—24, 1992; 702—708.
    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.

16. Methods of Design-Oriented Analysis: The Quadratic Equation Revisited
    Proc. IEEE Frontiers in Education, Twenty-Second Annual Conference, Vanderbilt University, Nov 11—15, 1992.
    The conventional formula for quadratic roots suffers from two defects: it is High Entropy, and it is computationally inaccurate when two real roots are widely separated.
    An improved formula is suggested that overcomes both defects. Both roots are expressed in terms of a single parameter F that contains the radical sign and is a unique function of the single parameter Q that determines the nature of the roots. Both roots are computed in terms of F with the same computational accuracy, and the Low Entropy format exposes the useful design-oriented result that, for well-separated real roots, F approaches unity so that the radical disappears and both roots reduce to simple ratios of the original quadratic coefficients.

17. The N Extra Element Theorem
    (with Vatché Vorpérian), IEEE Trans. on Circuits and Systems, Vol. 45, no. 9, 919—935, Sept. 1998.
    The N Extra Element Theorem (NEET) is an alternative means of analysis for any transfer function of any linear system model, not restricted to electrical systems. Its principal distinction from conventional loop or node analysis is that a simpler reference system model in the absence of N designated "extra" elements is solved first, and the N extra elements are then restored via a correction factor.
    No calculation is performed upon a model containing any of the designated extra elements, and the final result is obtained by assembly of sequentially obtained results in a "divide and conquer" approach that is potentially easier, shorter, and which produces lower entropy forms than does the conventional approach.
    The approach throughout is to show how the NEET theorem can be useful in practical Design-Oriented Analysis.
