Spectral Analysis | CROSPEC

CROSS SPECTRAL DENSITY – [CROSPEC]
Outputs the cross-spectral density of two signals.

CATEGORY
Spectral analysis

DESCRIPTION
Outputs the cross-spectral density by doing a Fast Fourier transform on both signals and returning cross-spectral density.

RESULT VARIABLES AND PARAMETERS

Magnitude (m)	Cross-spectral density magnitude
Phase_Angle (a)	Cross-spectral density phase
Signal_X	First signal to use for the cross-spectral density
Signal_Y	Second signal to use for the cross-spectral density
Window	Type of windowing applied to the analyzed samples. Refer to the beginning of Spectral analysis category to have a short description. [0: Rectangular,1: Hanning, 2: Hamming, 3: Blackman]

EXAMPLE
Here are the results of the cross-spectral density of:
x=sin(pi*2*15*t)
y=sin(pi*2*15*t+90*360/(pi*2))+sin(pi*2*28*t+90*360/(pi*2))
