Stick a resistor in series, about a 20K and a 022mf cap to ground after that resistor. Start with that and see where that takes you. A standard r/c time contant, totally passive. To calculate the length of the slew it's R (resistance in ohms) x C (capacitance in farads) = Time (in seconds). hope this helps. - P --- In PLAN_B_analog_blog@yahoogroups.com, Monroe Eskew <monroe.eskew@...> wrote:

Hi Peter, On the RC filter, could you explain why you need to ground it? This diagram doesn't have anything going to ground: http://en.wikipedia.org/wiki/RC_filter Thanks, Monroe On Mon, Dec 22, 2008 at 12:11 AM, (i think you can figure that out) <peter@buzzclick-music.com> wrote:

Hi Peter,
On the RC filter, could you explain why you need to ground it? This
diagram doesn't have anything going to ground:

Thanks,
