利用 FFT变换进行谐波分析 ,非整周期采样会带来较大的误差。传统的解决方法是采用频率跟踪技术实现采样的整周期性。提出了一种新的解决方法 ,有效的利用计算机的计算能力 ,用数值计算的方法极大地节省硬件的开销。在虚拟仪器软件开发过程中使用 ,证明了该方法的可靠性
Harmonic analysis using FFT transform, non-integer period sampling will bring greater error. The traditional solution is to use frequency tracking technology to achieve the entire sampling period. A new solution is put forward to make effective use of the computing power of the computer. The method of numerical calculation greatly saves the hardware overhead. Used in the virtual instrument software development process, the reliability of this method is proved
