摘要
为了实现对转频变化的振动信号的分析 ,提出了软件整周期采样。其核心是利用数学中的插值法 ,在不改变硬件采样频率的条件下 。
In order to realize the analysis of vibrantion signal whose frequency is rotationally changed,the soft ware whole periodic sampling is proposed.The method of interpolation in Math is used to obtain the renewsampling of original signal without changing the hardware sampling frequency.
