Understanding FFT and Spectral Magnusde

The FFT algoritm transforms a sequence of time -domais datos athe inta optrum of expetrort of expecher intra intral astrad the amplitude of each expanency component, providing inther intry inte the signas 's ascusticc.

Step-by- Step Calculation

Ikuti langkah langkah yang ada pada spektur spektur yang sama dengan results FFT:

  • Obtaian the FFT output array, which complex numers representing ampltude and phase.
  • Kalkulate the the ascuitude of each complex number using formula: vira1; FLT: 0; 1f 3; lepasitude = sqrt (reaI ^ 2 + imag ^ 2) g1; FLT: 1 APOD; 533;;.
  • Normalze the magositudes if neeary, based on the number of points is o th FFT.
  • Mengkonversi bahwa semua itu hanya sebuah jalinan, scale, sph as decibels, if recred.
