Record that contains essential parameters for the vectored signal filters.
The number of filters is specified by nFilter.
Note that all the signal filters have the same on/off control signal, rising time, and initialization type,
which are specified by use_strokeTime, strokeTime and initValve respectively.
However, they can have different initial valves, specified by yValve_start.
strokeTime to 30 seconds so that it is the same as for pumps.
Otherwise, pumps may work against almost closed valves.
