A two-wire air line has the following line parameters: R' = 0.404 (m/m), L0 = 2.0 (H/m),

A two-wire air line has the following line parameters: R' = 0.404 (mΩ/m), L0 = 2.0 (μH/m), G' = 0, and C' = 5.56 (pF/m). For operation at 5 kHz, determine (a) the attenuation constant a, (b) the phase constant b, (c) the phase velocity up, and (d) the characteristic impedance Z0.
