Physics · Network Analysis
The driving-point impedance Z(s) of a network has a zero at s = -3 and complex conjugate poles at s = -1 ± j1. If the DC impedance Z(0) = 3, then find the expression for Z(s).

Share:
- 1Z(s) = 2(s - 3)s2 - 2s - 3
- 2Z(s) = 3(s - 3)s2 - 2s - 2
- 3Z(s) = 2(s + 3)s2 + 2s + 2✓
- 4Z(s) = 3(s + 3)s2 + 2s + 3
Correct answer
Z(s) = 2(s + 3)s2 + 2s + 2
