Note 47. Inverse z Transform via Partial Fraction Expansion:Case 2: All Poles Distinct with M ≥ N in System Function (Explicit Approach)

This note presents a procedure for computing the inverse z transform for system functions in which all poles are distinct and the degree, M, of the numerator equals or exceeds the degree, N, of the denominator. The procedure uses polynomial division to convert the improper rational function, H(z), into the sum of a polynomial, C(z), and a proper rational function, HR(z).

In order for a rational function to be expanded as a sum of partial-fraction terms, the degree of the numerator must be less than the degree of the denominator. In cases where MN, the system function must be restructured as the sum of a ...
