WebThe Fourier transform of the convolution of two signals is equal to the product of their Fourier transforms: F [f g] = ^ (!)^): (3) Proof in the discrete 1D case: F [f g] = X n e i! n m (m) n = X m f (m) n g n e i! n = X m f (m)^ g!) e i! m (shift property) = ^ g (!) ^ f: Remarks: This theorem means that one can apply filters efficiently in ... WebDesmos doesn't natively support complex numbers. It does support parametrics though, so you can specify the x and y coordinates using the trigonometric functions. Reply
