In telecommunication system the decoder, usually a speaker, converts the electrical signals into the sound waves.
purposes we can collapse the encoder and the decoder into the medium for we never care about the details of the encoder and the decoder in particular. The changes in encoder and the decoder can be considered to be the changes in the medium. Thus sender, message, medium and receiver are the important components of this basic communication model. (A Communication Model, 1)
Application of the Basic Model to Group Communication: Since this a communication model it helps the groups members to communicate amongst themselves as well as with the others. This model also helps the group members access information from Internet.
Communication amongst the group members by telephone, mobile phone: Suppose that some of the group members are located at different sites. Communication mode via mobile would be by the above model. In this case each of the group member who would make a call would act as a sender. The microphone in the mobile instrument would convert the sound waves into the waves. In this case air would act as the medium for carrying the waves as mobile is the wireless instrument. Ultimately the group member at the other end would receive these waves by his mobile.
