Series R, then shunt C. It will shrink it somewhat as well, but if you
are then converting to square waves, as would seem sensible, then it
won't matter. Not entirely sure why you want to put in this added
delay though - it is just an extra inaccuracy on top of the real delay
you want to measure.
With a square wave the peaks don't matter. You are triggering the
counter from the edges.
