Digital signal processing
![An example of the 2D discrete wavelet transform that is used in [[JPEG2000]]. The original image is high-pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low-pass filtered and downscaled, yielding an approximation image; this image is high-pass filtered to produce the three smaller detail images, and low-pass filtered to produce the final approximation image in the upper-left.](https://commons.wikimedia.org/wiki/Special:FilePath/Jpeg2000 2-level wavelet transform-lichtenstein.png?width=200 "An example of the 2D discrete wavelet transform that is used in [[JPEG2000]].

Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency.

Examples of use of digital signal processing
1. The SP5050 has DSP (digital signal processing) that helps with reducing background noise, which is quite helpful here.
2. The company specialises in digital signal processing and analogue chips used in mobile telephones, music players and other electronic gadgets.
3. Its audio quality is enhanced even more with Digital Signal Processing (DSP), canceling out excess noises and echoes. «We are committed to providing convenient communications in the car — and out of it too.
4. May 16 2006 01:03 When a chip design company set up by one of Shanghai‘s top universities unveiled an advanced new "digital signal processing" computer chip in 2003, government officials and state media made no effort to contain their enthusiasm.
