A frequency tracking method is proposed.The synchronism sampling is achieved to improve the measuring precision of frequency and phase difference. 本文提出一種頻率跟蹤方法，可以在不過(guò)零開(kāi)始采樣的情況下，實(shí)現整周期采樣，保證頻率和相位差測量的精度。
This paper introduces a full period sampling method based on the resampling technology used in the sampling of rotor system vibration signals. 介紹了一種應用重采樣技術(shù)的旋轉機械振動(dòng)信號的整周期采樣方法。
