Question
Let X(2) be a causal LTI system with its poles and zeros located in the unit circle. Further,assume that the ROC includes the unit circle. We can express this system generically as: X(z)=A \frac{\prod_{k=1}^{M_{1}}\left(1-\alpha_{k} z^{-1}\right)}{\prod_{k=1}^{N_{1}}\left(1-\gamma_{k} z^{-1}\right)} where M1 are the n
