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_XFirst signal to use for the cross-spectral density
Signal_YSecond signal to use for the cross-spectral density
WindowType 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]


SYNTAX

[m,a]=crospec(x,y,2)


CHARACTERISTICS
Data type support
Double Floating point

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))
