"The thesis consists of two parts. In part 1, a series of updated formulas for calculating different PCB (Printed Circuit Board) transmission line impedance, capacitance and propagation delay time are introduced. The accuracy of these formulas is evaluated for typical circuit board dimensions. A web-based calculator that applies these updated formulas is developed to provide a simple tool for estimating the PCB transmission line parameters.

In part 2, a brief introduction to IBIS (I/O Buffer Information Specification) is presented. IBIS data is compared to the information required by the UMR PCB EMI Expert System. Enhancements to the IBIS standard are proposed that would permit all of the information required by PCB EMC Expert Systems to be a part of standard IBIS model"--Abstract, page iii.
