Logic Devices

Abstract

As described earlier, every problem in the world of logical algebra has either a ‘true’ solution or a ‘false’ solution. The ‘true’ and ‘false’ states are presented in terms of logic signals, that is, as electrical voltages. The ‘true’ condition is usually defined as a logic ‘1’ signal and the ‘false’ condition as logic ‘0’. The operation of any logic circuit can therefore be described by means of a table containing 1’s and 0’s which define the state of the input signals and output signals. Such a table is known as a truth table.
