Exact fourier transformation

  1. May 24, 2015 #1

    I am having a bit of trouble with calculating the fourier transformation of a harmonic load.

    I have the function f(t) = A * sin(ωt) in the time-domain.

    I would like to represent this function in the frequency domain.

    What would be its amplitude?

    Thank you

    It is a delta function at ω with amplitude A.
