Draw the block diagram of a generalized communication system and explain it briefly

Explanation

Every communication system has three essential elements : 1. Transmitter 2. Medium /Channel 3. Receiver .
The block diagram is shown in Fig.

In Communication system, the transmitter and the receiver are located at two different places separate from the transmitter.
The channel is the physical medium that connects. The purpose of transmitter is to convert the message signal produced by the source of information into a form ,Suitable for transmission through the channel. If the output of the information source is a non- electrical signal like a voice signal , a transducer converts it to electrical form before giving it as an input to the transmitter .when a transmitter signal propagates along the channel it may distorted due to channel imperfection. Moreover , noise adds to the transmitter signal and the receiver receives a corrupted version of the transmitted signal . The receiver has the task of operating on the received signal . It reconstructs a recognizable form of the original message signal for delivering it to the user of information .
