Frequency. To make yourself less vulnerable in this area, you must differentiate between valid and invalid rejection.

频率在这个领域工作不要太敏感，你需要区分对不同的拒绝进行区分。

I/Q imbalance problem causes finite rejection in the image frequency band, and the image interference will alias into the desired signal, severe distortion will occur.

不平衡问题将会造成接收机的镜像干扰排斥能力大幅降低，镜像干扰将使得欲接收的信号严重失真。

This added voltage is mainly power line frequency and its effect on the voltmeter reading will depend upon the normal-mode rejection capability of the meter.

这个相加的电压主要为电源频率的信号，其对于电压表读数的影响决定于电压表的串模抑制能力。
