B&K Pulse PL Functions

[DOFxyz]

Does any one know how to do the following PL function in B&K Pulse PL language:

Result = CPSD / sqrt (PSD)
Where:
CPSD is the Cross-Power Spectral Density of two signals x & y
PSD is the Power Spectral Density of one of the signals
sqrt is the Square Root.

Cheer.

What stops you from collecting data and doing that offline? In another program like excel, Matlab, C, ...

No I don't, but the answer will bear a striking resemblance to the spectrum of one of the signals.

SIGlease see FAQ731-376 for tips on how to make the best use of Eng-Tips.

Apologies for the delay.

You are right Greg. The result Should be very similar to one of the signals but "enhanced", I think! And with a "relative" phase angle between the reference and the signal.

I need these measurements "live". It is the bases of InvBEM. Which calculates the "Inverse Pressure" which is a complex value.
