From frequency field Angle the phenomenon ofsignaldistortion is analyzed, and the principle of observing and measuring the micro-distortionofsignal by using spectrum analyzer is explored.
从频域角度分析了信号失真现象，并探讨了频谱分析仪观测微小失真度的原理及若干问题。

It also have another conclusion on both in the process of image signaldistortion happens, distortion, this is inevitable.
由此也得另一个结论既转播过程中图像信号会发生畸变、失真、这是不可避免的。

This paper analyzes quantitatively, based on paired echo principle, distortion performance of linear FM signal by method of computer analogous design.
