In this algorithm, the digital differential filtering (DDF) is used to process the sampled signals, the timing component of signal is improved, and therefore the convergence speed is quickened.

该方法用数字差分滤波对采样信号进行处理，提高了信号中的定时分量，从而加快了算法的收敛速度。

But the timing of the appearance of these component words in the written record seems to make this assembly unlikely.

然而从文字记录来看，这几个词的出现时间产生了矛盾，组合在一起也就不太可能。

The orthogonal analog phase lock loop is used to get the timing information of the impulse radio system and the multi-path component separation.
