The digital signals storage technology is developing rapidly in these years also , especial the optical storage technology 数字信号的存储技术也发展迅速,特别是近几年的光存储技术。
At the same time , the period of optical signal storage in delay lines is also altered and the delay precision of optical fiber delay lines is improved 针对理想情况下的延时、未采用改变光源波长时的初始延时,以及改变波长后的修正延时分别做了仿真计算,结果表明延时精度得到了显著提高。
