Abstract :
This paper presents an optimization-based 2-D filter design procedure that utilizes the recently derived symmetry constraints in gamma domain. The gamma domain transfer function has significant coefficient sensitivity advantage compared to the same procedure applied to the conventional q-operator based design with the same symmetry constraints
