FFTWとは 意味・読み方・使い方

Since an evaluated value E represents an integrated value of FFTW and an integrated value of FFT1 in the form of an SN ratio, the evaluated value E gradually becomes a large value in accordance with an increase in an extent that periodic noise other than the frequency component belonging to the original screen is included.例文帳に追加

評価値Ｅは、ＦＦＴＷの積分値とＦＦＴ１の積分値とをＳＮ比の形で表したものであるので、本来のスクリーンが持つ周波数成分以外の周期的ノイズが含まれる度合いが増えるのに伴い次第に大きな値になる。 - 特許庁

When a first frequency spectrum is represented as FFT1(i, j), a second frequency spectrum is represented as FFT2(i, j), and a weight coefficient obtained from the first frequency spectrum is represented as W(i, j), a multiplied weighted frequency spectrum FFTW(i, j) is represented as W(i, j) × FFT2(i, j).例文帳に追加

第１の周波数スペクトルをＦＦＴ１［ｉ，ｊ］、第２の周波数スペクトルをＦＦＴ２［ｉ，ｊ］、その第１の周波数スペクトルから得られる重み係数をＷ［ｉ，ｊ］と表せば、乗算した加重周波数スペクトルＦＦＴＷ［ｉ，ｊ］はＷ［ｉ，ｊ］×ＦＦＴ２［ｉ，ｊ］と表させる。 - 特許庁
