Using matlab for Spectral Analysis, Fourier Analysis, Filterbank Analysis

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.
