The F(s) is ∞ ∫ f(x)e Where - x is a real number.
- f(x) is a function on x.
- s is a real number with the inverse unit of x, e.g., if x is time, s is a Frequency.
- F(s) is the transformed function.
*i*is the square root of -1.
There is also an inverse transform, from s to x. The Fourier transform is used to determine what sine-like components make up a particular periodic function, i.e., break a signal down into its harmonics. mathematics)Referenced by:
