Origin fft f

WitrynaEine schnelle Fourier-Transformation (FFT) ist eine effektive Methode zum Berechnen der DFT. Wird die FFT anstatt der DFT verwendet, kann die Berechnungskomplexität von O ( n2) auf O ( n log n) verringert werden. Beachten Sie, dass das Eingabesignal von FFT in Origin komplex und von beliebiger Größe sein kann. WitrynaF (u,v) 即为 f (x,y) 的二维频谱,它表明了该信号在 x 向频率 u 及 y 向频率 v 处的分量,它仍包含实、虚两部分。 从逆变换的定义式看,信号 f (x,y) 仍可视作是复指数 e^ {i2\pi (ux+vy)} 与(复)权系数 F (u,v) 乘积的线性组合。 展开复指数,有: e^ {i2\pi (ux+vy)}= [cos (2\pi ux)cos (2\pi vy)-sin (2\pi ux)sin (2\pi vy)]+i [sin (2\pi ux)cos (2\pi vy)+sin (2\pi …
