Computes the cross power spectrum and returns the results as the real and imaginary parts of the cross power spectrum.
A value that affects the output coefficients when window type is Kaiser, Gaussian, or Dolph-Chebyshev.
If window type is any other type of window, this node ignores this input.
This input represents the following information for each type of window:
Default: NaN—Causes this node to set beta to 0 for a Kaiser window, the standard deviation to 0.2 for a Gaussian window, and s to 60 dB for a Dolph-Chebyshev window
Time-domain window to apply to the signal.

Default: Rectangle
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Sample period of the time-domain signal in seconds.
Set this input to 1/fs, where fs is the sampling frequency of the time-domain signal.
This input is available only if you wire a 1D array of double-precision, floating-point numbers or a 1D array of complex double-precision, floating-point numbers to signal x or signal y.
Default: 1
Real part of the cross power spectrum of the input signals.
Start frequency, in Hz, of the spectrum.
Frequency resolution, in Hz, of the spectrum.
Real part of the cross power spectrum.
Imaginary part of the cross power spectrum of the input signals.
Start frequency, in Hz, of the spectrum.
Frequency resolution, in Hz, of the spectrum.
Imaginary part of the cross power spectrum.
