review: rm abbrev from heading. consistent terminology. add link to help resolve forward reference. |
Remove incoherent and unsourced claim by User:Mr.Mani Raj Paul. What is a DCT2 (as opposed to a DCT), what specific algorithm is it being used in to provide better compression, and where are the numbers? |

===Digital signal processing===
DCT plays a very important role in [[digital signal processing]]. By using the DCT, the signals can be compressed. DCT can be used in [[electrocardiography]] for the compression of ECG signals
The DCT is widely implemented in [[digital signal processors]] (DSP), as well as digital signal processing software. Many companies have developed DSPs based on DCT technology. DCTs are widely used for applications such as [[encoding]], decoding, video, audio, [[multiplexing]], control signals, [[signaling]], and [[analog-to-digital conversion]]. DCTs are also commonly used for [[high-definition television]] (HDTV) encoder/decoder [[integrated circuit|chips]].<ref name="Stankovic"/>
