Digital Signal Processing is the science of using computers to understand signals. Signals are found in many cases in our ordinary life. It’s found in your must-have cell phone, your HDTV, and your camera. It’s used in the military, in such cases as radar and sonar, “smart” bombs, and in every vehicle. DSP accomplishes a wide variety of objectives such as filtering, speech recognition, image enhancement, data compression,

One widely used device that uses Digital Signal Processing is the Compact Disk. This revolution in music changed the way music can be reproduced. CD’s music quality far exceeds the quality of its predecessors, the record and audiotape. The CD works by storing the music on it main surface, which is shiny. The digital information is stored in a series of pits burned on the surface with a laser.

Reed Solomon encoding involves combining the data and left and right stereo channels for error detection and correction. The errors found during playback are corrected, concealed, or muted. The error is corrected by using redundant data found in the encoding scheme. Adding new signals between adjacent samples conceals it. It’s muted by setting the volume to a zero value.

Digital Signal Processing is used in a wide variety of applications. Most of them dealing with reproducing something, whether it is an image, a sound, or a data file
