Hey everyone.

Has anyone got the formulas for calculating phase of 1st-4th order active/passive low/high pass filters? (including peaking 2nd order HP filters used for bassboost/EQ circuits). Also I need formulas for phase of parametric EQ circuits. This is so I can calculate the group delay from it and put it in a spreadsheet I have been making which models various alignments, etc. If anyone can supply these, it would be greatly appreciated!

Thanks!
Adrian
