The aim of this project is to develop a low power from transmitter to be used in specialized application such as local area network. Frequency modulation has several advantages over the system of amplitude modulation (AM) used in the alternate form of radio broadcasting. The most important of these advantages is that an FM system had greater freedom from interference and static various electrical disturbances, such as those caused by thunder storms and car ignition systems, create amplitude modulated radio signal that are received as noise by AM receives. A well-designed FM receiver is not sensitive to such disturbance when it tuned to an FM signal of sufficient strength also the signal to noise ratio in an FM system is much higher that that of an AM system. FM broadcasting stations can be operated in the very high frequency bands at which AM interference is frequency sever, commercial FM radio stations are assigned frequencies between 88 and 108 MHZ and will be the intended frequency range of transmission.
