The system distortion is inevitable in wide-band analog quadrature receiver because of the existing of amplitude and phase errors, the performance of receiver become worse.

由模拟器件构成的宽带正交解调接收机会由于正交通道的幅相不一致性造成整个系统的失真，进而影响整个接收系统的性能。

Then it studied the pulse waveform distortion from two aspects of the amplitude spectrum and phase spectrum.

随后从脉冲信号的幅度谱和相位谱两个方面研究了脉冲波形失真情况。
