摘要
频域电磁探测仪器已广泛地应用于地球物理勘探，由于受到中短波广播信号的干扰，接收系统需要对接收信号进行调谐滤波等处理。文章研究了一种基于单片机的具有存储、自动切换波段和及时自动修正功能的调谐控制器，并给出了测试电路和测试结果。
The frequency domain electromagnetic detection instrumeatation has been widely used in geophysical detection. For medium short wave broadcast signal disturbance, received signal should be tuned for following signal process in receiveing system. A tuning controller based on single chip corresponding test-circuit and test-curves are also presented in this paper.
