Design and make of FM stereo transmitter for subdistrict
Abstract:With the development of social,people have a high require to tune quality,FM stereo transmitter also is the foundation problem of wireless communication,so research for the domain is being more and more attention.
First,this paper retrospects the development history of transmitter,describes the state of research and development and the prospect of future development,discusses the conception、theory and manufacture methods of subdistrict of FM stereo transmitter,in the meantime,compare FM transmitter with AM transmitter in some aspects.
This paper major in design and make a model of FM stereo transmitter for subdistrict,spread extent:3—5Km,especially suit for the broadcast communication of school 、factory and corporate. The design and make of FM stereo transmitter for subdistrict is in the help of BA1404 to stereo modulation,then the stereo signal convey to the module of MEC002A for frequency modulation and radio frequency amplification,finally,transmitter the signal to sky though antenna.
