The traces have a length of 0.254 m (10 in.) and are terminated to ground
with 65 . They are driven by a 1-V 65- source, with 100-ps rise
and fall times. Analyze the crosstalk noise using the approximate model
from Section 4.3.2 and modal analysis, and compare your results with
simulation. Do all of the results agree? If not, why not?
4-13 Use modal analysis to:
(a) Calculate the modal impedance and velocity for the three-coupled-line
case in Problem 4-3.
(b) Simulate a 0.5-m coupled length and compare your results to those
obtained using SLEM analysis.
4-14 Develop expressions for the forward and backward crosstalk amplitudes
for the circuit shown in Figure 4-17, in which the victim line is open
circuited at the near end.
4-15 Use modal analysis to derive equations for the near- and far-end crosstalk
amplitudes for the terminated coupled pair shown in Figure 4-22.
4-16 Project : Develop a tool (Matlab, C

++

, etc.) to perform modal analysis for
an arbitrary number of coupled lines, using the inductance and capacitance
matrices as input.
