In physics and mathematics, the Fourier transform (FT) is a transform that converts a function into a form that describes the frequencies present in the original function. The output of the transform is a complex-valued function of frequency. The term Fourier transform refers to both this complex-valued function and the mathematical operation. When a distinction needs to be made the Fourier transform is sometimes called the frequency domain representation of the original function. The … Web6 Jan 2013 · Homework Equations. I was thinking of using the geometric series 1/ (1+q) = for q = e^ (-2*x), as the hyperbolic secant is 2*e^ (-x)/ (1+e^ (-2*x)) . And then you need to multiply the hyperbolic secant with e^ (iωt) and integrate from -∞. …
