I don't get the LP corner freq 85KHz... So simple question for you: Which RC components makes the 1st order LP filer? Cheers, Tom Edited by user 15 years ago  | Reason: Not specified

I would like to test out 100KHz corner and compare, thus need to calculate new C in the RC filter. I guess the C1..4 are the C's in the RC filter, or? And Rx, Ry, .., Rz are the R's in the RC filter?
