| 采用移相的原理,将无谐波失真的标准信号移相后与被测的失真信号相叠加,同时使标准信号的相位与被测的失真信号中的基波的相位相反,而两者的幅度值相等,结果将基波成份抵消而保留了谐波成份,由此而测出谐波失真度。 |

| Abstract: |
| Using the principle of phase shift, the standard signal of nil harmonic
distortion after phase shifting will be added to the distortion signal of measurand
repeatedly. At the same time the phase of the standard signal is opposite from that
of the fundamental wave among the distortion signal of measurand, but the amplitude
value of both is equal. As a result, the fundamental wave component is cancelled out
and the harmonic component is kept, so that harmonic distortion can be measured. |
