Matlab: Spectral Analysis, Fourier Analysis, Filterbank Analysis

  1. 1. Matlab:Spectral, Fourier and Filter-bank analysis<br />
  2. 2. Spectral Analysis algorithms<br />
  3. 3. Spectral Estimators<br />Power spectral density (psd) measures power per unit of frequency and has power/frequency units.<br />Mean-square (power) spectrum (msspectrum) measures power at a specific frequency.<br />Pseudospectrum (pseudospectrum) returns a pseudo spectrum that does not have any units.<br />
  4. 4. Using ‘fdatool’ for spectral analysis<br />Type ‘fdatool’ in the matlab command window.<br />
  5. 5. Using ‘fdatool’ for spectral analysis<br />Use the following settings:<br />
  6. 6. Using ‘fdatool’ for spectral analysis<br />Select the ‘design filter ‘ option and wait till the filter is designed ..<br />
  7. 7. Fourier analysis<br />Fourier analysis breaks down a signal into constituent sinusoids of different frequencies.<br />
  8. 8. Visit more self help tutorials<br />Pick a tutorial of your choice and browse through it at your own pace.<br />The tutorials section is free, self-guiding and will not involve any additional support.<br />Visit us at www.dataminingtools.net<br />
