The amplitude modulation signalling system (AMSS or the AM signalling system) is a digital system for adding low bit rate information to an analogueamplitude modulatedbroadcast signal in the same manner as the Radio Data System (RDS) for frequency modulated (FM) broadcast signals. A digital system is one that uses numbers, especially binary numbers, for input, processing, transmission, storage, or display, rather than a continuous spectrum of values (an analog system) or non-numeric symbols such as letters or icons. ... In telecommunications and computing, bit rate (sometimes written bitrate) is the frequency at which bits are passing a given (physical or metaphorical) point. It is quantified using the bit per second (bit/s) unit. ... An analog or analogue signal is any variable signal continuous in both time and amplitude. ... Amplitude modulation (AM) is a form of modulation in which the amplitude of a carrier wave is varied in direct proportion to that of a modulating signal. ... This article or section does not cite its references or sources. ... Radio Data System, or RDS, is a standard for sending small amounts of digital information using conventional FM radio broadcasts. ... Frequency modulation (FM) is a form of modulation which represents information as variations in the instantaneous frequency of a carrier wave. ...
This system has been standardized by ETSI (TS 102 386) as an extension to the Digital Radio Mondiale (DRM) system. The European Telecommunications Standards Institute (ETSI) is a standardization organization of the telecommunications industry (equipment makers and network operators) in Europe, with worldwide projection. ... Digital Radio Mondiale (DRM) is an international non-profit consortium committed to designing and implementing an open-source platform for digital radio broadcasting around the world, especially on shortwave. ...

The AM Signalling System, AMSS — does your radio know what it is listening to?, article in the EBU technical review (01/2006).
AMSS has based its activities on the belief that the development of Islamic thought is vital for the prosperity of the Muslim world and for the continuity of the Islamic intellectual heritage.
AMSS strives to serve the interests of the larger Muslim community by bringing together Muslim and non-Muslim scholars in an academic setting to examine and define Islamic perspectives on issues of global concern that contribute to the prosperity of Muslims around the globe and the betterment of humanity.
