crosstalk2Crosstalk II Calculation and SLEM Topics 2 Crosstalk and Impedance Superposition Examples SLEM Cross Talk and Impedance Impedance is an electromagnetic parameter and is therefore affected by the electromagnetic environment as shown in the preceding slides. In the this second half, we will focus on looking at crosstalk as a function of impedance and some of the benefits of viewing crosstalk from this perspective. 3 Using Modal Impedance’s for Calculating Cross Talk 4 Any state can be described as a superposition of the system modes. Points to Remember: Each mode has an impedance and velocity associated with it. In homogeneous medium, all the modal velocities will be equal. Superposition of Modes For a two line case, there are two modes Positive Going Voltage Positive Goi……
