六、噪声信号的时间域分析噪声信号的波形表达了它的时间域特性.不稳定的噪声信号的波形是不断变化的,所以难以观察.如果信号中伴随着干扰就更无法分辨.因此,除了有规则的信号外,波形图说明不了信号的特性,遂使信号时间域分析的应用受到了限制.如果想根据波形图来比较两个噪声的异同,则几乎是不可能的.为了在实际环境中提取噪声信号进行分 Time Domain Analysis of Noise Signals The waveform of a noise signal expresses its time domain characteristics. The waveform of an unstable noise signal is constantly changing and therefore difficult to observe. If the signal is accompanied by interference, it is even more inaccessible. Therefore, There are rules of the signal, the waveform can not explain the characteristics of the signal, then the application of the signal time domain analysis is limited.If you want to compare the two noise according to the similarities and differences between the waveform, it is almost impossible. In the extraction of noise signal for points
