The capacitance per unit length and the characteristic impedance of a lossless transmission line are C and Z0 respectively. The velocity of a traveling wave on the transmission line is
1
\({{\rm{Z}}_0}{\rm{C}}\)
2
\(\frac{1}{{\left( {{{\rm{Z}}_0}{\rm{C}}} \right)}}\)
3
\(\frac{{{{\rm{Z}}_0}}}{{\rm{C}}}\)
4
\(\frac{{\rm{C}}}{{\rm{Z}}}\)
