    Appendix C — Windowing C-1 Introduction The theoretical requirement for inverse FFT is for the data to extend from zero frequency to infinity. Side lobes appear around a discontinuity due to the fact that the spectrum is cut off at a finite frequency. Windowing reduces the side lobes by smoothing out the sharp transi-tions at the beginning and at the end of the frequency sweep.
