time domain display

The program, which is coded in C, puts time and frequency domain analysis, graph display and plotting together into one integral unit, capable of analyzing and studying any kinds of partial response.

该程序用C语言编程，将时域一频域分析、绘图、打印结合为一体，可对各种类型的部分响应进行分析研究。

It produces the primary signal first to carry on the display of time domain, the display of frequency domain and frequency spectrum, and compose the observing signal; finally it carries on the correlation analysis again after the signal filtered to remove the harmonic interference signal.

首先是对原始信号进行时域波形显示，频域频谱显示，初步观察信号的组成，最后再对滤波后的信号进行相关分析，除掉谐波干扰信号。

Then data is processed and displayed dynamically, and the processing methods contain: time domain waveform, spectrum analysis, power spectrum analysis, waterfall display and etc.

之后对信号进行实时分析处理并动态显示，分析方法包括时域波形、相关分析、频谱分析、谱差分析、功率谱分析、倒谱分析、瀑布图、轴心轨迹等。

A time domain display method of wavelength of tunable fiber ring laser based on filter the characteristics of WDM was successfully demonstrated. Under the multi-wavelength scanning mode and consecutive wavelength mode, the changes of wavelength were observed in time domain.

进而提出了利用波分复用器的滤波特性来实现光纤可调谐环形激光器多波长变化的时域显示方法，并在多波长扫描模式和连续波长模式下，观测到了时域上波长的变换。
