scipy.fftpack 和 numpy.fft 的区别 When applying scipy.fftpack.rfft and numpy.fft.rfft I get the following plots respectively: Scipy: Numpy: While the shape of the 2 FFTs are roughly the same with the correct ratios between the peaks, the numpy one looks…
http://blog.csdn.net/pipisorry/article/details/51050297 快速傅里叶变换 NumPy中,fft模块提供了快速傅里叶变换的功能.在这个模块中,许多函数都是成对存在的,也就是说许多函数存在对应的逆操作函数.例如,fft和ifft函数就是其中的一对. import numpy as np from matplotlib.pyplot import plot, show x = np.linspace(0, 2 * np.pi, 30) #创建一个包…
