Abstract

This project is about constructing an MP3 FM modulator with additional of FM microphone in hardware. MP3 FM modulator is a device that will enable audio sources from computer, Discman, MP3 player, TV audio and others to be played through MP3 FM Modulator, and also for the FM microphone that will enable the system generates and conditions to voice signals. FM transmission and the resultant signal is frequency modulated. The intended receiver for the transmitted signal is a conventional FM radio. The carrier will exist in the FM broadcast band that ranges from 88MHz to 1 08MHz. MP3 FM modulator enable people who are in same building but want to listen the same MP3 through their radios by just tuning to the frequency of FM modulator. For the FM Microphone enable communication between multiple cars on a road trip by tuning user's cars radio to the transmitting frequency. The main objectives project is to design and construct MP3 FM modulator by adding FM microphone in hardware and to investigate MP3 output signal. The fmal result is users will be able listen to the MP3 music through the radio by using this device instead of using separate audio system or can speak by using microphone on the device through the radio. Therefore it can save the money to buy the more high quality speaker, and able to extend MP3 audio playback capabilities.
