On slide 6 it would be good to say that while there is this 32 ns dead
time, that is usually insignificant compared to the dead time associated
with the input signal staying above threshold.
The FADC will not see a second pulse unless there has been time for the
signal to fall back below threshold; this time depends on the threhsold
and the first hit's amplitude but will very often be greater than 32 ns.
