The singlechip has come out since the 1970s, compared to is valued peoples and the attention by the extremely high performance price, therefore the application is very broad, the development is very quick. The application of SCM has changed the design idea and method of the traditional control system. Previously used by most of the hardware circuit of the control function, is the MCU software methods to achieve. With the combination of hardware or software to replace hardware and can improve the control system performance is called the micro control technology. STC89C54 Monolithic integrated circuits characteristic is the volume is small, the integration rate is high, the weight is light, antijamming ability, is not high to the environment request, the low in price, the reliability is high, the flexibility is good, the development is easier. What this design uses is the TEA5767 chip, it is promotes by PHILIPS Corporation in view of the low voltage application single chip digit harmonious FM stereophonic receiver chip. In the TEA5767 chip integrated the complete IF frequency selection and the frequency discrimination system, only need the very few low cost periphery part, be possible to realize the FM rad
