I have a measured signal (time domain) which I take the FFT of. I have a measured frequency dependent sensitivity (magnitude and phase (radians) as a function of frequency) which I need to apply to the measured signal. In effect perform a frequency dependent weighting to the measured signal's FFT. I calculate the complex signal for the sensitivity magnitude and phase before dividing this into the FFT of the original signal. I then take the IFFT of this which should give me something like the original signal shape but it does not.
Is my method correct?
