摘要：
FFT has relatively large errors in the condition of asynchronizing sampling, and therefore is not satisfied when high harmonic parameter accuracy is requested. To some extent, interpolating windowed FFT algorithm for harmonic analysis can be used to improve the accuracy. The error bounds of the algorithm by computer simulation is analyzed, which shows that in the harmonic analysis application, the errors of interpolating windowed FFT algorithm are relatively large in some condition and the error bounds should be used to evaluate the accuracy of the algorithm.
