Signature¶

def sdynpy.signal_processing.sdynpy_srs.temporal_moments(x: numpy.ndarray, dt: float) -> Dict[str, float]

Compute temporal moments of a sampled signal.

Parameters¶

• x : ndarray Input signal amplitudes with shape (n_samples,).

• dt : float Sampling interval.

Returns¶

• dict

• Dictionary containing:

• - "energy" : float

• Signal energy.

• - "tau" : float

• Time centroid.

• - "duration_rms" : float

• Root-mean-square duration.

• - "skewness_metric" : float

• Cube-root form of the third central temporal moment.

• - "kurtosis_metric" : float

• Fourth-root form of the fourth central temporal moment.

• - "rea" : float

• Root energy amplitude.

Notes¶

This function follows the intent of MATLAB gtempmom and is used to compute metrics for each generated acceleration history.
