Power Spectrum Estimation

The Power Spectrum Estimation library provides a number of blocks for spectral analysis. Many of them have correlates in Signal Processing Toolbox software, which are shown in parentheses:

• Burg Method (pburg)

• Covariance Method (pcov)

• Magnitude FFT (periodogram)

• Modified Covariance Method (pmcov)

• Short-Time FFT

• Yule-Walker Method (pyulear)

See "Spectral Analysis" in the Signal Processing Toolbox documentation for an overview of spectral analysis theory and a discussion of the above methods.

Signal Processing Blockset software provides two demos that illustrate the spectral analysis blocks:

• A Comparison of Spectral Analysis Techniques (dspsacomp)

• Spectral Analysis: Short-Time FFT (dspstfft)
