- Hi,
- Could anyone help me with the actual scale
- factors required to obtain the correct
- harmonic components(Amplitudes) for the components
- obtained by using a DFT/FFT and:
- a) Hanning Window
- b) Hamming Window
-
- The input sequence values are multiplied by the
- window coefficients before performing the DFT/FFT
- on the new sequence values.
