摘　　要：为实现多部通信机在近距离内以临近的频率互不干扰的正常工作,有效方法就是在接收机的输入端和输出端接入具有实时调谐功能的窄带高Q滤波器.本文提出了基于单片机的UHF电调滤波器的实时调谐设计,给出硬件结构图以及驱动和检测单元电路,最后给出设计流程.The method to make several communicators work normally within a short distance with similar frequencies is to embed high Q value band-pass fibers in both input-terminal and output-terminal of the receiver. The design of a real time tuning UHF electrically tunable filter based on single chip computer is given. And the hardware structure diagram and drivers, detection unit circuit design and flow diagram are shown.
