Information processing in digital domain

Digital signal processing requires the understanding of signal dynamics under different conditions. The processing of information in digital domain needs accurate and precise signal values. In the engineering sense, information is a measurable quantity, and a complete information theory exists, which enables the engineer to determine the rate of information transmission. Communication is concerned with the sending or conveying of information from one place to another, the transferred information is called a message. Digital signal processing has become the backbone of many products/peripherals like modems, hard disk drives, multimedia and image processing system.
