Hello,
I have two questions
1) Does diadem v8.0 & v8.1 use SAE J211 Oct 88 or Mar 95 for CFC filtering? (I suspect it's 88 as it is in the mathamatical background of the help, but I need to be sure)
2) What is the difference between the two?
I need this information to determine the correct ISO channel filter class code i.e.
A or E
B or F etc.
Thanks for you time

Hello lewis.may,
the CFC filter algorithm in Diadem is a Butterworth 4-pole phaseless filter according SAE J211 Mar 95, Appendix C. We are using this implementation also for our current version 11.

Have the CFC filters been updated to SAE J211 July 2007?

A filter which meets J211 '95 should meet the criteria specified in J211 2007
