摘要
根据短波 SFH /MFSK系统接收单元中中频信号的特点 ,提出了一种全数字式的超前—滞后跟踪环路的实现方案 ,并采用可编程逻辑器件 isp LSI1 0 1 6集成实现 ,最后给出了测试框图 ,实验表明该方案简单可行 ,工作可靠 ,适合短波
Based on the characteristics of intermediate frequency(IF) signal in short wave SFH /MFSK receiver. A fully digial lead lag PLL for tracing is studied and practised in this paper. The whole of design is integrated with ispLSI1016, and finally test block diagram is presented. Experiments indicate that the scheme is simple, feasible and reliable. It is suited for the short wave SFH /MFSK system.
