HW5 Solution Set Corrections

2a, 2c, 3b: The poles and zeros in some graphs are not consistent with the given results. The given results are correct, the graphs need be modified.
3a: The final result should be: X(z)=z(2z-5b/12)/(z-b/6)(z-b/4), giving zeros of z=5b/24 & z=0.
3b: X(z)=0 when z -> infinity, so infinity is alsoÊa zero.
3e: There is a pole at z=0.
