噪声发生器

And with Fourier transformation or its inverse transformation,the graph of this signal in the other domain is updated.

随着电子技术的不断发展，计算机技术与仪器技术结合得越来越紧密，出现了大量的任意波形发生器，它们能产生的波形不断丰富，除上面提到的基本波形外，还能产生Chirp信号、Sinc信号、MultiTone信号、脉冲信号以及各种噪声信号等。

The measuring deviation of reverberation time at low frequency in reverberation room is large.

针对混响室低频混响时间测量的偏差大这一问题，提出对随机噪声信号进行限幅或改用一系列单频信号发生器作稳定激发可显著改善测量结果的偏差。

In this paper,An idea on the design of arbitrary waveform synthesizer which based on high speed digital and analog circuits is introduced.

文中介绍了一种基于高速数模电路的任意波形发生器设计思路及其工程实现模型，并就其相位噪声、杂散电平等性能加以分析。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
