帮我看看这道题!拉氏变换到z变换
show briefly how the following s-plane features map into the z-plane and explain the significance of the results in each case:
(1) a line of constant damping ratio;
(2) an infinite strip in the left hand half of the s-plane of width,where A is the sampling frequency
头疼死了 题都还读不太懂···

Laplace transform 是用 s=jw, Z transform 是用的 z=e^jw
Z(s)=e^s
damping rotio ζ 是二阶系统中的常数. 让我想想.
