Q1. The characteristic impedance, Z, of a transmission line may be determined from the complex formula Z² = (R + jωL)/(G + jωC)

Determine in the polar rule, r < θ, EACH of the following for a transmission line where

R = 1.8 ohms, ω = 10⁴, L = 0.15×10^-3 henry, G = 4.4×10^-6 ohms and C = 1.3×10^-9 farads:

(a) Z² (9)

(b) Z, given that from De Moivre's Theorem, (r < θ)ⁿ= rⁿ < nθ for any value of n; (4)

(c) 1000/Z (3)
