| Abstract: | Based on the transient free digital phase lock technique,the method of designing a precise timing board for target range measurement is presented in this paper. The functions of the board include generating the time signal with high precision and high resolution,timing,keeping time,storing and displaying the time values of external trigger signal,Experimental results prove its feasibility and validity. |
