| 1. | The thesis firstly addresses the real - time performance of spectral zoom analysis algorithms . complex modulation based zoom algorithm is a classical one of such algorithms , in which samples are modulated , decimated , filtered , spectrally analyzed and re - sorted
在这种算法里，对长采样数据复调制，把欲分析的频段的中心频率移到零频点，然后重采样、低通滤波得到欲分析的频段，再做fft分析。 |
