Power Spectrum Estimation

Power Spectrum Estimation
The Power Spectrum Estimation library provides a number of blocks for
spectral analysis. Many of them have correlates in the Signal Processing
Toolbox, 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.
The DSP Blockset provides two demos that illustrate the spectral analysis
blocks:
•A Comparison of Spectral Analysis Techniques (
dspsacomp)
•Spectral Analysis: Short-Time FFT (
