FFTの基礎（日本語字幕付き）

[@mamorumotohasi9348]

This lecture is not FFT, I think it is FT. All right??

[@Yasu22359]

Are you saying that, this lecture is focused on FT, (strictly DFT), right? It's true that FFT itself denotes the algorithm which can calculate DFT with O(n log n) complexity, but most people in this field say DFT as FFT in my experience.
