Electrical performance of pulses propagating in Printed Circuit Boards (PCBs) is determined by the characteristic impedance, differential impedance, and terminating impedance of both single-ended and differential pairs. In this paper, numerical values are evaluated for the characteristic impedance, differential impedance, and common mode impedance of microstrip and strip transmission lines embedded in a PCB stack up. These numerical values are also plotted for different values of frequency, ratios of signal width to signal height above a ground plane, and signal separation to signal height.
