It is composed of two modules, the emitter and the received. It has several types of emitters, transmission channels, receivers, modulators and demodulators, in order to configure various digital transmission systems. For instance, it permits to compare the advantages of several transmission systems over others, including those fibre optic based, or to analyse interference phenomena between channels.
