摘要
介绍了一种用频率扫描抽取指定频率振动分量有效值的方法实现硬件频谱分析的工作原理。实践证明这种频谱分析法具有占用内存小 ,硬件电路简单 ,实现方便的优点。
A method of frequency spectrum analysis is introduced, which be realized by collect the virtual value of appoint frequency vibration through scanning frequency. It has been proved that this kind of frequency spectrum analytic approach has more merits and little expenses of memory and the circuit of hardware is simple, realization is convenient.
