COMPUTE POINT-WISE SQ-DIFFERENCE WITH VARIANCEFFT

Computes the point-wise squared difference of a curve from its variance, using an FFT-based variance calculation. Use this worker to quantify how much each sample point deviates (in squared terms) from the signal’s overall variance.

When to use

Classification: process.

Tagged: curve, fft, point-wise, signal, squared_difference, transform, variance.

Inputs

Label ID Type Default Required Description
Curve curve vector   Input time-history or XY curve (vector of paired X/Y values) whose point-wise squared deviation from variance will be computed; optional — leave unconnected only if the worker is used in a default/passthrough context.

Outputs

Label ID Type Description
Sq Difference from Variance curve_variance_o1 vector Output curve (vector) containing the point-wise squared difference between each sample of the input curve and the FFT-derived variance of the signal.
