1) overall harmonic distortion
整机谐波失真
2) harmonic distortion
谐波失真
1.
In order to prevent short-circuit of the same leg of a full-bridge inverter when the power switches turn on/off, there used to be a dead zone inserted in the control signals, which may lead to the harmonic distortion in the system.
为了防止桥臂在上下两管开通和关断时出现桥臂直通问题,需要在控制信号中加死区时间,这会给系统带来谐波失真。
2.
The harmonic distortion is one of the important performances of the broadband power amplifier,because some harmonic waves of the low part of the broadband is in the working-band.
对于宽带功率放大器,有些低频端的谐波正好在工作频带内,因此谐波失真是衡量宽带功率放大器的一个重要指标。
3.
The harmonic distortion of the double side band(DSB) algorithm for the audio directional loudspeaker is investigated.
依据一种新型扬声器——声频定向扬声器的基本工作原理,从理论上给出了DSB算法中调制系数对输出信号谐波失真影响的详细推导过程;并指出调制系数越小,失真度越小,但带来的负面效应是小的调制系数将使输出的信号功率相应变小。
