Editing Automatic gain control (section)

== Recovery times ==

As in all automatic control systems, the temporal dynamics of AGC operation may be important in many applications. Some AGC systems are slow to react to the need for gain changes, while others may react very rapidly. An example of an application in which fast AGC recovery time is required is in receivers used in Morse code communications where so-called [[QSK operation (full break-in)|full break-in]] or QSK operation is necessary to enable receiving stations to interrupt sending stations mid-character (e.g. between dot and dash signals).
