3a stops execution of 2a
1b is output after time t1
4a starts timer t2
5a starts timer t1
4b is output after time t2
6a to 8b: repeated as from 2a
1a starts timer t1
2a starts timer t2
3a starts timer t1 again (retrigger)
4a starts timer t2 again (retrigger)
5a…10a restart timer t1 and t2
9b is output after t1 (referred to 9a)

Processing as in example 3. Edge 5a
switches output "High". Edges 6a and
7a are filtered out due to the quick
succession.
Processing as in example 3. The last posi-
tive edge (7a) maintains the output sig-
nals on "High" level.
