Abstract
Crossbar switch array employs two linear conductors having resistors thereon, with horizontal and vertical crossbar conductors connected to linear conductors between the resistors. All resistors have identical value, so that when a switch is closed, voltage readings taken at one end of each of the linear conductors permit calculation of the number of resistors passing current in each linear conductor where a constant current source is provided. An analog signal is developed which is proportional to the row and column of the closed switch.
