EE2 Mathematics Solutions to Example Sheet 4: Fourier Transforms
3) To find the Fourier transform of the non-normalized Gaussian f(t) = e−t2 we first complete the square in the exponential f(ω) = ∫ ∞ −∞ e−iωt−t2 dt = |
What is the ξ in the Fourier transform?
Continuous Fourier Equation
Note that these equations use a ξ (the Greek letter Xi) to imply frequency instead of ω (Omega) which generally refers to angular frequency (ω = 2πξ).
The Fourier transform of a time dependent signal produces a frequency dependent function.
