Considering that the modular function of fractional Fourier transform of LEM signal is symmetrical, unilateral and strictly monotone, this method employs global-first-local-second search algorithm to obtain the main ridge slice of LEM signals.

该方法利用LFM信号的分数傅立叶变换模函数具有对称性，且单边单调的性质，采用先全局后局部方式搜索LFM信号主脊切面。

The hardware used for analog-to-digital conversion of video signals is called a frame grabber.

作为电视的信号类比到转变为传送信号的硬件叫做一个体系的核心。

When connected to a camera that has been reset, there are no previous timing pulses to synchronize to and the frame grabber needs to be driven by separate timing signals to enable it to interpret the incoming video.

当连接到重置过的相机上时，无法被原来的时序脉冲同步化而需要单独的时序信号驱动，这样的帧捕获才能中断输入视频。

You, Fraulein, will listen carefully. Learn their signals so that you can call them when you want them.

你，小姐，得仔细听，记住他们的哨声，下次叫他们时就用得着了。

The fact that no free oscillation spectra have so far been reported from ring lasers is consistent with amplitudes of our synthetic Sagnac signals and current noise levels of these sensors.

迄今为止，事实上环式激光中没有记录到自由振荡谱，所得结果与我们得到的 Sagnac 合成信号的振幅及传感器的噪声水平相一致。

The frequency fluctuation of the stabilized laser is held within 5.6 MHz and better than 160 MHz of the free-running laser. The root of Allan variance of error signals reaches a minimum of 1.66×10 -11 when averaging time is 64 s, well within the precision needed for application.
