'''Equalization''', (British: '''equalisation''') is the process of adjusting the balance between [[frequency]] components within an electronic [[Signal (electronics)|signal]]. The most well known use of equalization is in [[sound recording and reproduction]] but there are many other applications in electronics and telecommunications. The circuit or equipment used to achieve equalization is called an equalizer.  These devices strengthen (''boost'') or weaken (''cut'') the energy of specific frequency [[Frequency range|bands]].

In telecommunications equalizers are used to render the [[frequency response]]—for instance of a telephone line—''flat'' from end-to-end. When a [[communication channel|channel]] has been "equalized" the [[frequency domain]] attributes of the signal at the input are faithfully reproduced at the output. Telephones, [[DSL]] lines and television cables use equalizers to prepare data signals for transmission.
