The RF Toolbox add-on to MATLAB [26] and several books (for example "Network scattering parameters" [27]) use this last definition, so caution is necessary. The "From S to T" and "From T to S" paragraphs in this article are based on the first definition. Adaptation to the second definition is trivial (interchanging T11 for T22, and T12 for T21 ...
In statistical models applied to psychometrics, congeneric reliability ("rho C") [1] a single-administration test score reliability (i.e., the reliability of persons over items holding occasion fixed) coefficient, commonly referred to as composite reliability, construct reliability, and coefficient omega.
The Readers' Guide to Periodical Literature is a reference guide to recently published articles in periodical magazines and scholarly journals, organized by article subject. The Readers' Guide has been published regularly since 1901 by the H. W. Wilson Company, and is a staple of public and academic reference libraries throughout the United ...
If you accept that the reflection coefficient is equivalent to the S11 scattering parameter of the load, and that Z0 is the impedance the load sees looking out of its port, i.e. the source impedance, then the formula as written contradicts the definition of S11 (see Scattering_parameters). S11 is defined as b1/a1; a1 is defined as (1/2) K1 (V1 ...
A Guide to information sources (or a bibliographic guide, a literature guide, a guide to reference materials, a subject gateway, etc.) is a kind of metabibliography. Ideally it is not just a listing of bibliographies , reference works and other source texts , but more like a textbook introducing users to the information sources in a given field ...
In telecommunications, return loss is a measure in relative terms of the power of the signal reflected by a discontinuity in a transmission line or optical fiber.This discontinuity can be caused by a mismatch between the termination or load connected to the line and the characteristic impedance of the line.
The initial elements of S-matrix theory are found in Paul Dirac's 1927 paper "Über die Quantenmechanik der Stoßvorgänge". [1] [2] The S-matrix was first properly introduced by John Archibald Wheeler in the 1937 paper "On the Mathematical Description of Light Nuclei by the Method of Resonating Group Structure". [3]
Krippendorff's alpha coefficient, [1] named after academic Klaus Krippendorff, is a statistical measure of the agreement achieved when coding a set of units of analysis.. Since the 1970s, alpha has been used in content analysis where textual units are categorized by trained readers, in counseling and survey research where experts code open-ended interview data into analyzable terms, in ...
