Abstract
If a rational function is defined by a Laurent series in an annular region, then we can construct a qd-table from its Laurent coefficients. The limits of certain rows and columns in this table give you information about the pole/zero structure of the rational function. This property was known for the column-pole connection [11] but is not for its row-zero connection.
