power spectrum using yule walker method

[hampis]

i am currently working on an algorithm and i need to add a power spectrum using yule walker method or modified covariance method or any other power spectrum estimation method except music and fft (periodogram) that i already did. can anybody help me?or does anybody have any other vi that calculates the power spectrum?

Hi hampis,

I posed a similar response on the yule walker forum.

If you're running LabVIEW 8.0 or 8.2 you can use the MathScript node to execute the aryule() function, which uses the Yule-Walker method to estimate autoregressive (AR) model parameters.

Here is more information on this command:
