Slope based fjlter BL3 mini presentation SAMPA Design Review Meeting Konstantin Münning Universität Bonn Helmholtz-Institut für Strahlen- und Kernphysik 23.01.2015
Slope based fjlter, principle g ( 0 )= f ( 0 ) (arbitrary) g' ( t )= { Slope ↑ if f(t)>g(t) 0 if f(t)=g(t) Slope ↓ if f(t)<g(t) upward slope downward slope simplifjed functional description of slope based fjlter • slope based fjlter is following directly the signal but is limited by maximal slopes for rising and falling • has some advantages compared to ALTRO MAF 2
Simulated operation BC2 & BC3 • Similar behavior of BC2 and BC3 • Failure of BC2 when base line moves too fast 3
Chaining BC3 → BC2 • Chaining BC2 after BC3 increases robustness of BC2 4
Resetting BC2 from BC3 • After timeout BC2 is reset to the baseline of BC3 5
