The following functions are specified as the real part of impedance function Z(s).
Find the function Z(s).
a) R(w) = 16 - 8w2 + w4 /1 +w8
b) R(w) = 2 + 4w2 + 3w4 + w6 / 1 + w8
c) R(w) = -w2 + 2w4 -w8/1 + w8
d) R(w) = 1- 2w2 + w4 / 1- 2w2 + w4 + 4w6
e) R(w) = (1- w2 + w4)2 /(w24 - 4w2 + 3)2 + w2( w4 - 6w2 + 8)2
