This Filter Prototype Board is developed within the multi channel time
interval counter and fine delay generator (Time Box) framework.
As explained in the ADC board
wiki our goal is
to determine the time of arrival of one incoming electric pulse.
In order to do that, we plan to transform the pulse's rising edge in an
"easier to observe" event. Indeed, if the pulse occurs between two
sampling moments, it is impossible to determine when it has occurred
with an higher precision than the sampling sampling period. The
precision can then be increased by transforming the rising edge of the
pulse into a damped sinewave which lasts several sampling periods and
can be reconstructed. By using mathematical interpolations, it is then
possible to determine when the rising edge did occur within the sampling
