Unformatted text preview: 3) a) For the coupled lines of problem 2, let s = w. Find the self and mutual inductances and capacitances for this structure. b) if a signal with a risetime of 0.1 ns is input to one of the lines, what is the spatial extent (m) of this signal? c) If the lines run parallel for 1.5 cm, what is the maximum value of the near end crosstalk normalized to the signal voltage? d) What is the normalized far end crosstalk voltage? 4) A pair of coupled, symmetrical TEM lines run parallel to each other a distance, l, that is /4 at the frequency of interest. The four port network for this structure is I 1 + V 1I 3 + V 3I 2 + V 2I 4 + V 4[ Z ] V S Z S Let ports 2, 3 and 4 be terminated in open circuits. Port 1 is terminated in a sinusoidal Thevinen equivalent circuit generator of source voltage V S and internal impedance Z S . The Zparameters for the four port are Find the voltages V 2 , V 3 and V 4 in terms of V S ....
