In part 1 of this series, we looked at the formula for the inverse discrete Fourier transform and manually calculated the inverse transform for a four-point dataset. Then, we used Excel’s ...

The inverse transform can create a time-domain waveform where no waveform has been before. In part 2 of this series, we used the discrete Fourier transform to convert a waveform from the time domain ...

I have the following situation: I have caluclated a Displacement Field Transform and have its Inverse. Now, I would like to use both as initial fixed transform and calculate another Displacement Field ...
