总谐波失真 Total Harmonic Distortion 总谐波失真简介 总谐波失真是指用信号源输入时,输出信号比输入信号多出的额外谐波成分。谐波失真是由于系统不是完全线性造成的,它通常用百分数来表示。所有附加谐波电平之和称为总谐波失真。一般说来,1000Hz频率处的总谐波失真最小,因此不少产品均以该频率的失真作为它的...
THD(Total Harmonic Distortion,总谐波失真): 谐波失真是指音箱在工作过程中,由于会产生谐振现象而导致音箱重放声音时出现失真。尽管音箱或耳机中只有基频信号才是声音的原始信号,但由于不可避免地会出现谐振现象(在原始声波的基础上生成二次、三次甚至多次谐波),这样在声音信号中不再只有基频信号,而是还包括...

THD stands for Total Harmonic Distortion and can be used to estimate the degree to which a system is nonlinear. A THD measurement can be made by applying a sine wave as an input to a system, and measuring the total energy which appears at the output of the system at harmonics of the ...

total harmonic distortion. Additionally, the synthesized signal contains only four harmonics, including the fundamental. This is confirmed by the table, which shows a large power reduction after 4 kHz. Therefore, repeating the calculation with only four harmonics does not change the total harmonic ...

To determine the total amount of nonlinear distortion, also known as total harmonic distortion (THD), a system introduces, measure the amplitudes of the harmonics the system introduces relative to the amplitude of the fundamental frequency.
