The cited article states: "The signal from the crankshaft position is also used to monitor if any of the cylinders misfires."
Other references state that what is monitored is the slight accelleration of the crankshaft at each firing. If this slight "kick" is not detected, it is recorded as a misfire. Another article mentioned that the system "has to be invulnerable to torsional oscillations" and other 'noise'. So I had things somewhat mixed up! A good reminder for me to check things out first.
