失真度测试仪 meaning in Chinese
distortion meter
Examples
- Most of analog distortion meters apply the method of suppressed first frequency . the lowest frequency that these meters can detect is 2hz
一般模拟式的失真度测试仪都采用基波抑制法，此类失真度仪所能测的最低频率为2hz 。 - The error of distortion which harmonic distortion meter detects can be least controlled 1 . the lowest frequency which harmonic distortion meter can detect is 0 . 0001hz . but , generally , this kind of meter is so costly and difficult to operate that the major portion of the distortion meters applies the method of suppressed fundamental harmonic
采用谐波分析法的失真度仪测得的失真度的最小误差可控制在千分之一以下，频率最低可达到万分之一赫兹，但普遍存在仪器价格较贵，操作繁琐的缺点，现在用的失真度测试仪大多是用基波抑制法。
