Signals and Systems Pdf Notes - SS Pdf Notes | SmartzworldIn signal processing , a signal is a function that conveys information about a phenomenon. A signal may also be defined as an observable change in a quantity. Any physical quantity that exhibits variation in space or time can be a signal used, among other possibilities, to share messages between observers. Also, it is stated that a signal may or may not contain any information. In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food. Signalling occurs in all organisms even at cellular levels, with cell signaling.

Signal processing is an electrical engineering subfield that focuses on analysing, modifying and synthesizing signals such as sound , images and biological measurements. According to Alan V. Oppenheim and Ronald W. Schafer , the principles of signal processing can be found in the classical numerical analysis techniques of the 17th century. Oppenheim and Schafer further state that the digital refinement of these techniques can be found in the digital control systems of the s and s. Around the same time, methods of signal transmission were being rapidly developed, as a new type of signal emerged called processing signals.
