THE DESIGN AND CONSTRUCTION OF A TRANSMITTER

ABSTRACT

This project as the name implies is chosen, designed and constructed with the intention of transmitting information such as musicals news entertainments programs and so on. And all these that are written above are being transmitted to the atmosphere using an electromagnetic, signal, and this particular project design and construction is exactly the type of electronics, instrument that are mainly used in a Radio Broadcasting House or Studio all over the world and ever in a communication place. This project was achieved using these electronics components like electrolytic capacitors for smoothing, resistors for current Oppositions, Bipolar transistors frequency transistor), Trank Circuit with a variable capacitor and a variable or adjustable induction connecting worries Vero board for circuit connection switch a transmitting Antenna which sends the signal to the air when connected, light emitting Diodes for power indication.  And in conclusion improvement or modification of this project was possible so that it’s efficiency will be increased.
