3rd order IIR filter
Posted: Fri Nov 20, 2015 3:03 pm
Hi,
I'd like to research a 3rd order LP and HP design, preferably as 'code' not 'assembly' so I can understand the logic.
Is there any such example ?
How can I calculate the coefficients for these cases? Most 'links' I find explain about bi-quads (2nd order) not 3rd order.
On the 'Dozius filter pack' I found a close example but it is coded as assembly.
Any 'blue code' example out there? (both LP and HP) ?
Rocko
