  BASIC ELEMENTS OF COMMUNICATION SYSTEM      INFORMATION SOURCE :   It produces message signal which we want to send.   It converts message signal to electrical signal .(it is also called as input transducer)     TRANSMITTER :   It converts the message signal to suitable form of propagating signal over communication channel.   The process of conversion is possible by modulation. And finally sends the signal through the channel.     CHANNEL :   The path for transmitting a signal is called channel.    It is a medium between transmitter and receiver ( wire / wireless ),use for signal transmission.                      NOISE :      The unwanted form of signal energy is known as noise.        It enters the communication system through channel.          RECEIVER :     The main fun...
