| Abstract: | A new method for measuring the harmonie distortion of transducers treasuring vibration is introduced in this paper. This method is called anaiyticul method which is simple, fast and with direct display. It is especially desirable for measuring harmonic distortion of transducers whieh have small signals and high accuracy. It is also recommended in this paper that a linear nondamping free vibration system of a single freedom degree can provide a stimulant source of sine wave with high purtity for measuring the harmonic distortion of transducers. |
