Classical filter design techniques return only one design from
an infinite collection of alternative designs, or fail to design
filters when solutions exist.
Threse classical techniques hide a wealth of alternative filter
designs that are more robust when implemented in digital hardware
or embedded software.
In this paper, we present (1) case students of optimal digital
IIR filters that cannot be designed with classical techniques,
and (2) the formal, mathematical framework that underlies their
We have automated the advanced filter design techniques
