Solutions to Common FFT Issues

To prevent aliasing, ensure the samlinging rate is ast least twice the highest component of the signul. Applying acute window functions, sph af o r Hamming windows, reduces spektral leakage.

  • Normalize FFT output rightly
  • Use zero- padding judiciously
  • Validate with test signal
