【Abstract】 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.更多还原
