WebWe've learned that to take a Fourier transform means to decompose a complicated function into a series of simple sine waves. The idea is that if you were to add those sine waves back up together, adding them together you would recover the complicated function that you began with. WebFourier transform is purely imaginary. For a general real function, the Fourier transform will have both real and imaginary parts. We can write f˜(k)=f˜c(k)+if˜ s(k) (18) where f˜ … banana donuts baked
