signal_strength

vallenae.features.signal_strength(data, samplerate)[source]

Compute the signal strength of a hit.

Signal strength is the integral of the rectified AE-signal over time. The unit of Signal Strength is nVs (1e-9 Vs).

Parameters:

  • data (ndarray) – Input array (hit)

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

Return type:

float

Returns:

Signal strength of input array (hit)
