typically contain larger numbers of coupled lines. In our earlier discussion we
noted that for even-mode switching, the effective inductance is increased by the
mutual inductances between lines, while the effective capacitance is decreased by
the mutual capacitance. We also know that for odd-mode switching, the effec-
tive inductance is decreased by the mutual inductances between lines, while
the effective capacitance is increased by the mutual capacitances. Finally, the
mutual inductances and capacitances for quiet lines do not change the effective
