【信号処理】離散フーリエ変換対：DFT, Discrete Fourier Transform

すでに行った，離散フーリエ級数，DFSとほぼ同じです． 信号の周期性の仮定をしていましたが，サンプリングされた信号では， 1周期分のサンプリングとみなせば，有限長データも同じです． 復習：フーリエ変換対 信号 $${x(t)}$$ の周期性に関して，無限長 ...

【信号処理】高速Fourier変換(1)，FFT, Fast Fourier Transform, N=4の場合 ...

この高速フーリエ変換という名前は分かりにくいと私は思っている． この名称は，新しいフーリエ変換の形式かと誤解させる節がある． 離散フーリエ変換の高速化アルゴリズムであるだけなのに． まずは，最も簡単な$${N=2}$$の場合にどのようにDFTが計算さ ...

Implementation of quantum and classical discrete fractional Fourier transforms

Two hundred years ago, Joseph Fourier introduced a major concept in mathematics, the so-called Fourier transform (FT). It was not until 1965, when Cooley and Tukey developed the ‘fast Fourier ...

Interpolated Discrete Fourier Transform-Based Noise Extraction and Analysis in Power ...

Abstract: In electrical distribution system measurements, noise arises from both sensor-related distortions and grid disturbances. Accurate noise extraction is crucial for identifying and mitigating ...
