rise_time

vallenae.features.rise_time(data, threshold, samplerate, first_crossing=None, index_peak=None)

Compute the rise time.

The rise time is the time between the first threshold crossing and the peak amplitude.

Parameters:

• data (ndarray) – Input array (hit)

• threshold (float) – Threshold amplitude (in volts)

• samplerate (int) – Sample rate of the input array

• first_crossing (Optional[int]) – Precomputed index of first threshold crossing to save computation time

• index_peak (Optional[int]) – Precomputed index of peak amplitude to save computation time

Return type:

float
