ABSTRACT

Intercom is the abbreviation of “Intercommunication” and refers to the communication by means of wires/cables between various individuals situated at comparatively distant location within a certain premises. The various locations are known as stations. The difference between an intercom and public telephone system lies in the fact that wires connecting the various stations do not cross any public place. The intercom circuit will let us talk with another person in a distant room. The kit will be in one room and speaker will be in other room. When a person speaks, his voice signals will be changed into electrical signal by a condenser mic and then the electrical signals generated will betransmitted through the circuit. The electrical signals at the other end will be converted into analog or voice signals by the speaker used and hence the person at the other end can hear the message. The unit having all components is called master unit and the unit having only the speaker is called slave unit.
