ABSTRACT
Digital logic networks are used in all devices that process information in digital form. Information – recorded or communicated facts, or data – takes a variety of physical forms when being stored, communicated, or manipulated. Information on the nature of a physical phenomenon is conveyed by signals that assume a finite number of discrete values, that is, it is expressed as a finite sequence of symbols. A signal is defined as a function of one or more variables, and a system is defined as an entity that manipulates one or more signals to accomplish a function, thereby yielding new signals.
