SURVEY OF RECENT GEOMETRIC-ANALYTIC WORK ON IMPEDANCE, POWER, AND NOISE TRANSFORMATIONS

摘要

A survey is made of recent geometric-analytic work on impedance, power, and noise transformations. Three basic research publications treating impedance, power, and noise transformations through bilateral two-port networks are briefly outlined. Analytically, the transformations consist in conformal, projective, and affine transformations. Geometrically, they are performed in the complex plane, in the Cayley-Klein models of two- and three-dimensional hyperbolic space, and in the Minkowski model of four-dimensional Lorentz space.
