Fine frequency resolution requires a small reference frequency and a correspondingly small loop bandwidth.

高的频率分辨率要求低的参考频率，这就相应地要求环路的带宽比较窄。

In order to make the track loop into lock quickly, the paper USES FFT spectral analysis to get fine frequency.

为了让跟踪环路快速入锁，这里还采用了FFT谱分析法对频率进行精捕。

By means of this technique, the signal frequency can been controlled with facility, accuracy, continuous phase and fine frequency resolution.

利用这种技术可以方便的实现高精度、连续相位、高分辨率的频率控制。

What the May 6 crash did show was that while high frequency trading may work just fine in normal market conditions, when trouble comes the markets become a mile wide and an inch deep.

The fine, though relatively small, is bound to give more ammunition to the anti-high frequency trading crowd, which is demanding regulators do something to stop this specialized form of computer trading, or at the very least slow it down.
