From 1934 to 1936, NEC engineer Akira Nakashima published a series of papers showing that the two-valued Boolean algebra, which he discovered independently, can describe the operation of switching circuits. His work was later cited and elaborated on in Claude Shannon's seminal 1938 paper "A Symbolic Analysis of Relay and Switching Circuits". The principles of Boolean algebra are applied to switches, providing mathematical tools for analysis and synthesis of any switching system.Yeet oof
Switching circuit theory provided the mathematical foundations and tools for digital system design in almost all areas of modern technology.
