STA/LTA algorithm for extracting transient and stationary part of the signal
Based on the synthetic signal (delta function) Introduced transient: different amplitude deltas
For testing I chose 4 delta functions:
- without any transient introduced (F1)
- with simple transient (F2)
- with more complex transient (F3)
- with added noise (F4)
[F4 - function with transient and introduced noise]
Evaluation of the efficiency of the set up parameters based on:
- percentage of transient detected
- ture ture detection of transient
- weighted average of two mentioned above parameters
Paramaters to be set:
- short term average STA
- long term average LTA
- threshold
- pre and post event time PEM
