Transcript

  • 1. Matlab:Spectral, Fourier and Filter-bank analysis
  • 2. Spectral Analysis algorithms
  • 3. Spectral Estimators
    Power spectral density (psd) measures power per unit of frequency and has power/frequency units.
    Mean-square (power) spectrum (msspectrum) measures power at a specific frequency.
    Pseudospectrum (pseudospectrum) returns a pseudo spectrum that does not have any units.
  • 4. Using ‘fdatool’ for spectral analysis
    Type ‘fdatool’ in the matlab command window.
  • 5. Using ‘fdatool’ for spectral analysis
    Use the following settings:
  • 6. Using ‘fdatool’ for spectral analysis
    Select the ‘design filter ‘ option and wait till the filter is designed ..
  • 7. Fourier analysis
    Fourier analysis breaks down a signal into constituent sinusoids of different frequencies.
