Please answer

Which of the following statements on the coefficients of the partial fraction expansion (residues) are TRUE The coefficients depend on the Region of Convergence. The coefficients are calculated using different methods for continuous-time and discrete-time systems. The coefficients must always be real. Selected Answer. 1 and 3 Answers: 1 and 3 3 2 1 None of the above.

Solution

1. As coefficients can be found for infinte series, so coefficients do not depend on (ROC) Region of convergence.

2. We can use same method for calculating the coefficients for continuous and discrete systems.

3. Coefficinets can be complex, so coefficients must always be real is not TRUE.

So the answer is NONE of the ABOVE.
