摘要
本文论述了数字锁相环在位置检测中的应用 ,设计了以数字锁相环为动态测量核心的新型数显装置 ,该装置充分利用了数字锁相环的相位误差累积作用 ,提高了数显装置的测量精度和测量速度。
This paper shows the application of digital phase\|locked loops in position measurement. The new type readout device used digital phase\|locked loops as core of motive measurement was designed. The device make the best of the character of digital phase\|locked loops, so that its measure precision and speed is enhanced.\;[
