Ahhh.. I'll take your word for it.  =]  That bit almost makes sense to me...
guess it's time to pick up a basic DSP book along with the ARM manual.  And
here I thought calculus was a stupid requirement for computer science...

Low pass filtering is required but it shoud match whatever is in the modem
spec. Usually, the transmitter and receiver have root raised cosine filters
for an overall raised cosine response, but it depends on when it was
designed.
