Signal Processing Sequence:
Signal processing is the study of mathematical tools that can be used to extract information from signals or to alter signals and systems to make them behave in a desired fashion. The signals in question come from a wide variety of application areas, such as communications, navigation, radar, imagery, speech, and even biology. A typical signal processing curriculum includes techniques such as evaluation of the spectrum of a signal, correction of the distortion in a signal or image due to the atmosphere, extraction of patterns and structure from a signal or image, system parameter estimation, and target detection. There is a heavy emphasis on linear algebra and statistical techniques. The strength of signal processing is that practitioners can work in many different fields, since the research focus is on the mathematical techniques rather than depth within a given application area.
