Total harmonic distortion

Refers to the input source,
Output signal more than the input signal additional harmonic components. Harmonic distortion is caused by In the system is not completely linear, it is usually expressed as a percentage. The sum of all additional harmonic levels is called total harmonic loss
true.

​

In general, 1000Hz

The total harmonic distortion at the frequency of the smallest, so many products are the distortion of the frequency as it index of. However, the total harmonic distortion and frequency must be 20-20000Hz measured within the entire audio range.

​

Total harmonic distortion shows that when the amplifier is working, the second and third harmonics generated by inevitable oscillations of the circuit or other resonances are superimposed on the actual input signal, and the signal output at the output end is not simply the same component as the input signal. But includes the harmonic component of the signal, the surplus of these harmonic components and the actual input signal comparison, expressed as a percentage of the total harmonic distortion.
