WebFourier Transform Notation There are several ways to denote the Fourier transform of a function. If the function is labeled by a lower-case letter, such as f, we can write: f(t) → F(ω) If the function is labeled by an upper-case letter, such as E, we can write: E() { ()}tEt→Y or: Et E() ( )→ %ω ∩ Sometimes, this symbol is WebJul 9, 2024 · Definitions of the Fourier transform and the inverse Fourier transform.
