Talk:Switching circuit theory

logic analogy
Using Boolean Algebra to study switching requires establishing an analogy between circuit state and logic level. Logic level 1 and 0 could for instance, be high voltage or low voltage, high current or low current, or high resistance or low resistance. Switch circuits usually use high and low resistance, i.e. contacts open or closed; it is important to note that closure allows current to flow in either direction. As a result, such circuits can have unusual topologies such as bridges, and also can have undesired phenomena such as "sneak circuits". Therefore, I think that a general discussion needs to start near here. --AJim (talk) 18:45, 23 June 2011 (UTC)

Isn't it a different name for Automata theory?
How is it different (or how it is related to) Automata theory? If it is the same, it should be merged, if it is a different theory, could somebody highlight the difference, please? Shcha (talk) 12:51, 18 June 2012 (UTC)

Misrepresentation of sources by possible Jagged-85 sock-puppet.
The article misinterprets the work of Stankovic et al []. What they are saying is that Switching circuit theory was probably independently discovered by several authors, at least according to a few sources from USSR and Japan. Basically Shestakov, Shannon and Nakashima all come with it. Soviet sources give credit to Shestakov while also recognizing contribution of Shannon. On the other hand Japanese sources, in particular Yamada gives priority to Nakashima. DMKR2005 (talk) 17:56, 31 May 2021 (UTC)


 * In this paper, Stankovic regards Nakashima as a pioneer. .Shesseon (talk) 17:47, 15 June 2021 (UTC)
 * I don't think so. The paper says that "The fundamentals borrowed from symbolic logic, like Boolean algebra[8], [10], [53], and algebra of logic [9], were suggested by Paul Ehrenfest [11],and further championed by Claude E. Shannon [55]. The same theoretical foundations were developed quite independently by the Japanese scholar Akira Nakashima [43] in a series of lectures at the Japanese Society for Informatics and related publications, and later elaborated by him and his associate Masao Hanzawa [44]. In the Soviet Union, theoretical foundations were considered by M. Tsimbalisty [80], and continued by V.I. Shestakov[56], [57], [58]1, followed by many others, as it can be seen from the enclosed List of Publications" DMKR2005 (talk) 19:03, 15 June 2021 (UTC)
