Project Abstract

<p> </p><p>An intercommunication system is nothing but the communication between two or more persons not close to one another. This does not mean we should categorize telephones, fax, teleprinters, telegraphs etc. an example of intercom system sine they are used in communication between people. Infact, intercom involves short distance places. It is limited in electronics, offices, and hospitals. </p><p>The intercom system under is a three way station type. This means that a person can communicate to the other at another station at his own convenient time. They call once another attention by the use of the tone generated by the use of tone generator.</p><p>Depress a button and the tone sounds, and the same switch is thrown to the intercom circuit thus they communicate.</p><p>This system to be used in solving the problem of poor communication in our department. Besides, it can be extended to some other offices by the addition this one may use a rotary switch</p> <br><p></p>
