cross power spectral density

[kiarash]

Hello

I can not figure out how to use "Cross Power Spectral Density" (CPSD)

in Labview. I know that Labview has something about

"Cross Power Spectrum" but I need Cross Power Spectral

Density, because I am going to measure the coherence which

needs CPSD as far as I know.

Thaks for your help

Hi kiarash,

I am not familiar with cross power spectral density or calculating coherence.  However, there are some other forum topics that might be useful for your application:
