The ForwardFFT Method performs a forward Fast Fourier Transform.
You must keep track how the transform is centered, as well as the scaling method, in the forward FFT in order to know how to de-center it during the inverse FFT. |
This method can be applied only to valid ImGearComplexObject Class object.
ImGearFrequencyProcessingVerifier.CanApplyForwardFFT Method can be called to check whether the operation can be performed or not.
