Variable notch filter

Post by bdoan » Sat Mar 07, 2015 1:57 pm


I have pared this code down and still have a useable, tunable notch.

What I need to figure is the relation between the POT value (for frequency) and the actual notch frequency.

;Frequency control
rdax pot0,1 ;get freq control
rdfx p0fil,0.01 ;average with filter
wrax p0fil,1
wrax f1,0
