1) clipping distortion
削波失真
1.
The discussion indicates that the bit error rate (BER) of the QAM signal is influenced by the optical modulation depth of the QAM signal,the clipping coefficient,the rate of clipping distortion and the Gaussion noise.
分析结果表明,QAM信号的误码率和QAM信号的光调制度、削波失真系数以及削波失真与高斯噪声之间的比例等都有密切的关系,激光器削波将严重恶化数字QAM信号的误码率。
4) diagonal clipping
对角削波失真;负向过调制失真
5) 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。
