1. Logical circuit elements

As it is known, any digital calculation — whether it is per­formed by 'pencil and paper' methods or with the aid of an automatic computer — must first be broken down into a se­quence of elementary arithmetical operations, such as addition, or multiplication. Each such arithmetical operation may be con­verted into a sequence of simple logical operations. It should be noted that a binary digit may take only two values — "zero" and "one". A logical proposition may be either true or false.

A symbolism and a set of rules suitable for manipulating 'yes or no' logical propositions was developed by George Boole, a self-educated genius who became Professor of Mathematics at Cork University in the middle of the 19^th century. The tech­niques of Boolean algebra are now extensively used by electri­cal engineers for the design and analysis of switching circuits. Both the arithmetic and control units of a computer consist of sets of switching circuits for directing and manipulating elec­trical pulse signals.

The process of combining a number of electronic circuits of known logical properties into an integrated system capable of performing special arithmetical or control functions is known as logical design.
