Source Word

Fourier transform

Noun

(mathematical analysis, harmonic analysis, physics, electrical engineering) A particular integral transform that when applied to a function of time (such as a signal), converts the function to one that plots the original function's frequency composition; the resultant function of such a conversion.

Japanese Meaning

フーリエ変換：時間領域の関数（例えば信号）を周波数領域の関数に変換し、元の関数の周波数成分を示す積分変換手法 / 数理解析、調和解析、物理学、電気工学などの分野で用いられる特定の積分変換 / 与えられた関数の各周波数成分の存在と大きさを明らかにする方法

What is this buttons?
