A new on-line digital solution for event timing setups

We present a linear method for the estimation of the occurrence time of events, based on a FIR digital filter running on a fixed point digital signal processor. With respect to least mean squares (LMS) methods, our approach allows a much higher event rate (>100 k events/s, i.e. ten times better than LMS) at the expenses of a somewhat worse time resolution (roughly two times worse than LMS).
