The complex voltage reflection coefficient Γ \Gamma \, is defined as the ratio of the reflected wave to the incident (or forward) wave.
) The blue circle, centered within the impedance Smith chart, is sometimes called an SWR circle (short for constant standing wave ratio). The Smith chart can be used to simultaneously display multiple parameters including impedances, admittances, reflection coefficients, S n n S_. It was independently devised by Tōsaku Mizuhashi ( 水橋東作) in 1937, and by Amiel R. The whisky colour chart below, as found on the Whisky Magazine website, is a 20-point scale representing the various colours of whisky with descriptors for each colour. How he came up with this is an untold story, but he provided a solution to the complex calculations on. The Smith chart (sometimes also called Smith diagram, Mizuhashi chart ( 水橋チャート), Mizuhashi–Smith chart ( 水橋スミスチャート), Volpert–Smith chart ( Диаграмма Вольперта-Смита) or Mizuhashi–Volpert–Smith chart), is a graphical calculator or nomogram designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits. The intimidating graph, developed by Philip Smith in 1939, is just about as bad as it looks. For the similar term Volpert graph, see Volpert graph (disambiguation).
