Abstract :
The authors present a method of generating one-variable Hurwitz polynomial (HP) using the properties of the positive definite matrices coupled with resistance matrices. Also, they test the two-terms separable-denominator transfer function and three-terms separable-denominator transfer function for their effectiveness in the design of noncircular, symmetric two-D filters with constant group-delay specification.
