电子线路综合实训论文 题 目：基于RDA5820的数控FM收音机 院 （系）： 信息与通信学院 专 业： 电子信息工程 摘 要 现在人们常使用的收音机为手动调频收台，使用较为麻烦，而且由于接收灵敏度不高，所接收的频段较窄。为了解决这些问题，本次采用RDA5807收音模块与单片机相结合，实现FM收音并显示频率。单片机自20世纪70年代问世以来，以极其高的性能价格比受到人们的重视和关注，所以应用很广，发展很快。单片机的特点是体积小、集成度高、重量轻、抗干扰能力强，对环境要求不高，价格低廉，可靠性高，灵活性好，开发较为容易，所以本次采用stc89c52单片机。此外，RDA5807模块具有65-108MHz全球FM接收频段相容的效果，具备噪声消除、软静音、低音增强，灵敏度高、噪声小、抗干扰能力强等功能，还可以具备频率显示功能，所以使用本模块很容易实现。 关键词：单片机；RDA5807；FM收音机 Abstract Now people often use radio FM radio station manually, using the more cumbersome, and because the receiver sensitivity is not high, narrow band received. To solve these problems, this time using RDA5807 radio module and microcontroller combined to achieve FM radio and display frequency. SCM since the 1970s came to an extremely high cost peoples attention and concern, it is very wide application, developed rapidly. SCM is characterized by small, highly integrated, light weight, strong anti-interference ability, less demanding on the environment, low cost, high reliability, flexibility, and development easier, so this uses stc89c52 microcontroller. In addition, RDA5807 module has 65-108MHz band FM receiver compatible global effect, with noise reduction, soft mute, bass boost, high sensitivity, low noise, strong anti-interference ability and other functions, can also have a frequency display, so the use of the modules can be easily achieved.
