Parametric Spectral Estimation

Burg, Yule-Walker, covariance, and modified covariance methods

Use parametric methods based on autoregressive models to estimate spectra.

Functions

Estimators

`findpeaks`	Find local maxima
`pburg`	Autoregressive power spectral density estimate — Burg’s method
`pcov`	Autoregressive power spectral density estimate — covariance method
`pmcov`	Autoregressive power spectral density estimate — modified covariance method
`pyulear`	Autoregressive power spectral density estimate — Yule-Walker method
`refinepeaks`	Refine peak value and location estimates (Since R2024b)

dB Conversion

`db`	Convert energy or power measurements to decibels
`db2mag`	Convert decibels to magnitude
`db2pow`	Convert decibels to power
`mag2db`	Convert magnitude to decibels
`pow2db`	Convert power to decibels
