介绍了一个基于解析信号和带通滤波的频率细化分析技术，讨论了其和传统的频率细化分析技术相比较所具有的特点，对离线测量，该技术在计算机上实现时，分析速度和最大细化倍数均比传统方法有较大提高，为基于计算机平台的虚拟仪器中的频率细化分析技术提供了一条崭新的实现途径。
This paper deals on the method of ZOOM FFT based on analytic signal and band pass filter, which is different from other methods of ZOOM FFT. It is used on computer with larger zoom ratio; higher compute speed and so on than other ways for offline testing. It provides a new method for the development of Virtual Instruments on ZOOM FFT analysis.
