Biography
Solving principal circuit-theoretical problems of the 1940s and 1950s posed by Wilhelm Cauer, Yosiro Oono established the so-called “classical network theory” named by Vitold Belevitch. Prof. Oono provided complete solutions to the problems of clarifying realizability conditions for linear passive n-ports and found their equivalent networks by developing mathematically rigorous theory. Since Prof. Oono's groundbreaking work is a general synthesis theory built on the principles only of linearity and passivity, it has widely influenced the development of sophisticated circuit designs for today's digital filters, active filters, and of signal processing. Concerning more general networks including active elements, Prof. Oono pointed out the existence of innovative singular elements known as a nullator and a norator, which are very useful for active network synthesis.
An IEEE Life Fellow, Dr. Oono is an Emeritus Professor of Kyushu University, Japan.
