Slope based fjlter, principle

• 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

upward slope downward slope

simplifjed functional description of slope based fjlter

g(0)=f (0) (arbitrary) g'(t)={ Slope↑ Slope↓ if f(t)>g(t) if f(t)=g(t) if f(t)<g(t)

3

Simulated operation BC2 & BC3

• Similar behavior of

BC2 and BC3

• Failure of BC2 when

base line moves too fast

4

Chaining BC3 → BC2

• Chaining BC2 after

BC3 increases robustness of BC2

5

Resetting BC2 from BC3

• After timeout BC2

is reset to the baseline of BC3
