Smith (1905вЂ“1987) and independently by Mizuhashi Tosaku, 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. Of course, we can also do this quite nicely on the Smith Chart. The only effort required is the reading and following of values along the circles. that in electrical engineering, a Smith chart is a common way of graphing the amount of a signal reflected by a telephone line A record of the entry may be seen at Wikipedia:Recent additions/2004/February. A Smith chart is a circular plot with lot of interlaced circles on it when used correctly, matching impedances with apparent complicated structures can be made without any computations.
