    detailed by Wallace (2007‚ p. 25) is of a ‘transmitter’ transferring a message or information to a ‘receiver’. The key area‚ and one that is easily overlooked‚ is the return route from the receiver back to the transmitter. One first needs to ‘decode’ the message - Has the receiver got the message? Have they understood the message? This is where ‘feedback’ is essential‚ i.e. when the receiver can show they have understood. This could be a much as the receiver repeating the message back to the sender

    valuables with this microcontroller based security system that will let us rest our head knowing that should anyone trying to break into our home‚ an alarm will go off and the police will be alerted immediately. The transmitter section continuously transmits IR rays which are received by the receiver section. The received signal is further amplified and given to the PLL section‚ where its frequency is locked to the transmitted frequency. When the IR signal is interrupted‚ the microcontroller starts working

    elements. The first five elements namely‚ Information Source‚ Transmitter‚ Channel‚ Receiver and Destination are all connected in a linear fashion. The sixth element‚ Noise Source‚ is connected to the Channel. The model is illustrated below (Figure 1). Figure 1: Mathematical Theory of Communication The Information Source is what produces the message. A Transmitter encodes the message into a signal and is passed through a Channel. The Receiver then decodes a message from the signal and is passed to

    Linear Model of Communication It is a one way model to communicate with others. It consists of the sender encoding a message and channeling it to the receiver in the presence of noise. Draw backs – the linear model assumes that there is a clear cut beginning and end to communication. It also displays no feedback from the receiver. • For example; a letter‚ email‚ text message‚ lecture. There are two main linear model which are used to explain the human communication process. They are .

    modes.”[1] Communication requires a sender‚ a message‚ and a recipient‚ although the receiver doesn’t have to be present or aware of the sender’s intent to communicate at the time of communication; thus communication can occur across vast distances in time and space. Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver has understood the message of the sender. Communication is transfer of information
