Understanding the nature of digital signals, binary, and other multi-level signal types do require an explanation of the two most prominent telecommunications types that exist, and examples of how they are applicable to specific devices, the binary is association and its function. (Please note that the majority of the information below are extracts from various websites, used to validate and support a theoretical premise; on which an understanding of multilevel signals exist. )
Analog and Digital Signals The term "analog" comes from the word "analogous" meaning something is similar to something else. It is used to describe devices that turn the movement or condition of a natural event into similar electronic or mechanical signals. For example a non-digital watch contains a movement that is constantly active in order to display time, which is also constantly active. Our time is measured in ranges of hours, minutes, seconds, months, years, etc. The display of a watch constantly tracks time within these ranges. In effect the data represented on a watch may have any number of values within a fairly large range. The watch 's movement is analogous to the movement of time. In this respect the data produced is analog data. Digital signals, on the other hand, are distinctively different. Digital signals don 't have large ranges, nor do they reflect constant activity. Digital signals have very few values. Each signal is unique from a previous digital value and unique from one to come. In effect, a digital signal is a snapshot of a condition and does not represent continual movement.
Binary Association Every electronic signal is broken down into binary language, classified as ‘0’ and ‘1’.
The most obvious example of digital data is that communicated on-board a computer. Since a computer 's memory is simply a series of switches
