Telecommunication Systems Manufacturers

Telecommunication systems are concerned with the transmission of information, or message, from one point to another. The origin of the message is referred to as the source and the destination as the sink. In order to effect this transfer of information the messages from the source are represented by a signal, which takes the form of a voltage varying with time. The basic elements of a telecommunication system are a transmitter that takes information and converts it to a signal for transmission, a transmission medium over which the signal is transmitted, a receiver that receives and converts the signal back into usable information. Signals can either be analogue or digital. In an analogue signal, the signal is varied continuously with respect to the information. In a digital signal, the information is encoded as a set of discrete values. Telecommunications devices convert different types of information, such as sound and video, into electrical or optical signals.
