View source for Physics:Amplitude modulation signalling system

The '''amplitude modulation signalling system''' ('''AMSS''' or the '''AM signalling system''') is a [[Digital data|digital]] system for adding low [[Bit rate|bit rate]] information to an [[Engineering:Analog signal|analogue]] [[Physics:Amplitude modulation|amplitude modulated]] [[Engineering:Broadcasting|broadcast]] signal in the same manner as the [[Physics:Radio Data System|Radio Data System]] (RDS) for [[Physics:Frequency modulation|frequency modulated]] (FM) broadcast signals.
This system has been standardized in March 2006 by ETSI (TS 102 386) as an extension to the Digital Radio Mondiale (DRM) system.

{{Outdated as of|year=2016|month=October|day=16|June 2011}}
AMSS data are broadcast from the following transmitters:

* LW
** RTL France: 234&nbsp;kHz
* SW
** BBC World Service: 15.575&nbsp;MHz

Formerly it was also used by:

* MW
** Truckradio 531&nbsp;kHz
** BBC World Service: 648&nbsp;kHz
** Deutschlandradio Kultur: 990&nbsp;kHz
