摘要
对 FSK移频信号的采样效率和频率分辨率进行了深入研究 ,提出了基于欠采样率 AD转换的移频自动闭塞信号高分辨率检测方法 ,并给出了系统检测装置的实现电路 。
Sampling efficiency and frequeney resolution of FSK signal are deeply studied,and a high resolution approach for detecting frequency shift auto blocking signal is put forward based on under rate AD convertion.The diagram of this detecting system is not only illustrated,but also analyzed to its real time property.
