更进一步讲，从随机激励中提取出来的模态参数同样会有畸变，并且在很多情况下，在测量结果中实际上看起来好像是有两个峰。
To go one step further, the extracted modal parameters from the random excitation will also be distorted, and in many cases, there actually appears to be two peaks as seen in the measurement.
限幅法是目前应用较为广泛的一类预畸变峰均比抑制算法，但其会引入额外的限幅噪声，从而对数据信号和导引符号造成干扰，恶化传输性能。
Clipping is a popular method to control the PAPR with distortions, but it introduces additional clipping noise, so as to distort the data and pilot symbols and degrade the system performance.
测量发现当电子束流增大到一定程度时，测出的弹性电子峰严重畸变，电子倍增器工作在饱和状态。
However, when electron current exceeds a certain value, an abnormal elastic electron peak can be observed, because the channeltron works in saturation mode.
