Question:

Let T = 0.05 s andE(s) = s+2 (s  1)(+1)


(a) Without calculating E(z), find its poles.

(b) Give the rule that you used in part (a). 

(c) Verify the results of part (a) by calculating E(z).


(d) Compare the zero of E(z) with that of E(s) .


(e) The poles of E(z) are determined by those of E(s) . Does an equivalent rule exist for zeros?
