ABSTRACT
The topic is the on-board audio converters with the developing in electron technology and the depressing of the cost of the production, carry-home audio device has become in common use in our life.At the same time ,autocar as well as coming into Chinese residenter’s life.It is very necessary to develop a facility which could link these carry-home audio device with sound system of the vehicle.We call this equipment ‘FM Emitter’.
The topic of this project is ‘vehicle –carry FM Emitter’.It is mainly research the BH1417F circuit base on the PLL technology which ensure the frequency modulation signal stabilized and the 3D stereo coding technology which hold on the timbre of the sound barrier.By using EDA software such as the Protel 99 SE, design SCH file and PCB file.Then purchase the components and equipments. Finally, jointing these components and equipments to a production which appease to prospective request.
Developing tool used is Protel 99 SE by Protel in 1999,which combine the emluator technology from MicroCode Engineering and the signal integrality technology from Incases Engineering Gmbh.
