You do if you want good noise immunity.

Take a look at the cycles though.  Compared to a 24F at anything near full
speed, the cycles used by this is a tiny fraction.  Let's say for example
the PIC is running at 30MHz instruction rate.  That's 30K instructions per
1mS sample.  1% of that would be 300 instruction, which is way more than the
filtering and peak detection would take.  Are you really so tight on CPU
cycles that a fraction of 1% makes a difference?
