In facsimile transmission and reception , adjustment of a reproduced picture to correspond exactly with the original by a phasing signal 在传真传输和接收过程中,为保证复现图象与原图一致,用定相信号进行的一种调整技术。
Press the feed button and check where the phase signal ( or similarity signal ) is recorded . use the scale having divisions 1 to 31 to read the position 按feed按钮并检查相位信号(或类似信号)是否有记录。 (使用1到31 `的刻度来读出相位的位置。
Although the work is based on the nonstationary signal of quadratic phase , the methods can also be extended to higher - order polynomial phase signal 论文的研究虽然是基于不高于二次相位项的非平稳信号,但是其思想方法也可以推广到更高阶的多项式相位信号。
