摘要
随着科学技术的发展,调频收音机的应用十分广泛,尤其消费类占有相当的市场。从分立元件组成的收音机到由集成电路组成的收音机,调频收音机技术已达到十分成熟的地步。
收音机从它的诞生至今,不仅方便了媒体信息的传播,也推进了现代电子技术和更先进的电信设备的发展。从普通的调幅收音机到高级调频收音机,调频收音机以较高的技术含量和较高的音质得到了广泛的欢迎。
本课题主要研究调频收音机的设计全过程,介绍一种基于51系列单片机的调频收音机,~,。该系统主要由电源模块、控制模块、显示模块和调频模块,功放模块组成。它以51单片机为核心,控制TEA5767调频芯片及LED数码管实现调频收音与显示频率,并通过功放播音。该设计将是一台工作稳定、高性能、体积小、易调谐、接收灵敏度高、参考频率选择灵活、可实现自动搜台的调频收音机。

Abstract
With the development of science and technology, FM radio is widely used, especially consumer occupies a considerable market. From ponents radio to consist of Integrated Circuits Radio, FM radio technology has reached a very mature stage.
Radio from its birth date, not only facilitate the media dissemination of information, but also promoted the modern electronic technology and the development of more advanced munications equipment. From the ordinary AM radio to senior FM radio, FM radio with high technology content and high quality has been widely ed.
The main topic on FM radio design process, based on the51 Series MCU FM radio, can realize the automatic frequency range between ~, adjustable. The system is posed of a power supply module, control module, display module and a modulation module, power amplifier module. With51 single-chip puter as the core control chip, TEA5767FM and LED digital control to achieve the FM radio frequency power amplifier and display, and the broadcast. The design will be a stable work, high performance, small volume, easy tuning, high receiving sensitivity, frequency reference selection is flexible, can realize the automatic searching FM radio.
Key words: FM radio;The 51 Series MCU; TEA5767 chip
