![]() ![]() They focus on the technical level, which concerns the problem of how to use a signal to accurately reproduce a message from one location to another location. Shannon and Weaver distinguish three types of problems of communication: technical, semantic, and effectiveness problems. The person receiving the call is the destination and their telephone is the receiver. They use the telephone as a transmitter, which produces an electric signal that is sent through the wire as a channel. For a landline phone call, the person calling is the source. The receiver translates the signal back into the original message and makes it available to the destination. The transmitter translates the message into a signal, which is sent using a channel. The source produces the original message. It was initially published in the 1948 paper A Mathematical Theory of Communication and explains communication in terms of five basic components: a source, a transmitter, a channel, a receiver, and a destination. The Shannon–Weaver model is one of the first and most influential models of communication. ![]() The five essential parts of the Shannon–Weaver model: A source uses a transmitter to translate a message into a signal, which is sent through a channel and translated back by a receiver until it reaches its destination. ![]()
