The design and implementation of multiple intercom systems that will operate without charge has always been a field of interest among many researchers and developers. This project presents the developments and potentialities of a bidirectional intercom system that allows bidirectional conversations from one place to another within a particular place such as offices, homes, workshops, warehouses. This writing project discussed an intercom system and its make-up component, operating applications and other relevant issues with respect to the intercom system. The basic element used in this project are tone generator, audio input source, audio amplifier, output device and medium (cable). As both microphones (input source) are always in operation, 1000uf capacitor was used in the power circuit to prevent loudspeaker from being picked up by the microphone included in the same box, causing a very unwanted and laud.
An internal communication system is a system that basically transfers information in the form of an electrical signal from one point to another within a confirmed location. It is also a private telecommunications system that typically allows two or more location to communicate with each other as the phone does. An intercom is also a personal telecommunications device that facilitates the exchange of messages between two or more places where standard vocal communication would be difficult or impossible due to distance or obstructions. This project of two-way intercom system consists of station linked to each using cable. It uses the full-duplex .modea process through which voice calls can be transmitted and received simultaneously, which means that the transmission medium is its wires between the two nodes and the headers typical of the nodes (separate speaker and microphone, good Isolation of the sound from the speaker to the microphone element).
