Digital Signal Processing deals with algorithms for handling large chunk of data. This branch

identified itself as a separate subject in 70s when engineers thought about processing the signals

arising from nature in the discrete form. Development of Sampling Theory followed and the

design of Analog-to-Digital converters gave an impetus in this direction. The contemporary

applications of digital signal processing was mainly in speech followed by Communication,

Seismology, Biomedical etc. Later on the field of Image processing emerged as another

important area in signal processing.
