    13. 13. S.I.E.T. GANGOH COMMUNICATION IS A PROCESS OF SHARING INFORMATION B/W TRANSMITTER & RECEIVER COMMUNICATION IS THE NECESSITY OF EACH HUMAN BEING TO BE CONNECTED WITH EACH OTHER TELEPHONES IS THE RAPIDLY BECOMING TOOL FOR THIS PURPOSE SOURCE RECEIVER I/P TRANSDUCER O/P TANSDUCER TRASMITTER CHENEL NOISE
