Abstract :
In double sideband (DSB) AM broadcasting two sidebands carry the same information. Indeed one sideband signal is enough to recover the baseband signal at the receiving end. Hence one of the sideband can be cut out from the DSB signal and is commonly known as single sideband (SSB) signal. Other than only transmitting one sideband signal, two different information carried in the individual sideband can be applied in the AM broadcasting to replace the DSB AM one. As a result only one carrier is necessary to transmit and receive two different kind of information. Not only the bandwidth efficiency is enhanced but also a useful multipurpose broadcasting system is established. In this paper independent sideband (ISB) AM broadcasting system for audio and information transmission is proposed and tested
