energy

vallenae.features.energy(data, samplerate)

Compute the energy of a hit.

Energy is the integral of the squared AE-signal over time (EN 1330-9). The unit of energy is eu. 1 eu corresponds to 1e-14 V²s.

Parameters:

• data (ndarray) – Input array (hit)

• samplerate (int) – Sample rate of input array in Hz

Return type:

float

Returns:

Energy of input array (hit)
