ABSTRACT
This chapter considers how decimal numbers can be represented in an electrical form by using a set of wires, one assigned to each separate digit where each digit, if available, carries a logical 1 on its designated wire and, if not available a 0. For the representation in the table to work, each wire has to be dedicated to represent a unique decimal value. Boolean logic is the method by which computations and decisions are carried out in digital computers. All logical manipulation within a digital machine is carried out by means of logic blocks: these blocks should be considered for their functionality, and for the purpose of design this is all that is necessary. There are a number of criteria that apply to the assembly of a logical function, all of which have to be provided through the use of logic blocks arranged in a particular order to accomplish the task required.
