There is a level of non-lineardistortion that is "good enough" relative to other flaws in the loudspeaker. Further reduction of this distortion brings no audible improvement.
The metering error considers the nonlinear effect of the voltage coil and current coil in watt hour meter under different order of harmonics and different distortion degree of input waveform.
计量误差考虑了电度表电压线圈和电流线圈在不同的谐波次数以及谐波大小时的非线性效应。

An analysis to the interference caused by non-lineardistortion in CATV system has been made, and a method for removing it has been offered as well.
