Chapter 16 Summary: Impedance
Impedance is composed of the three parasitic elements discussed in Chapters 11, 12 and 13, and it is a major property of transmission lines. Chapter 16 explains how to calculate the impedance of any transmission line, including the relationship between impedance, parasitic inductance, parasitic capacitance and parasitic resistance. Readers will learn why parasitic inductance and capacitance can be ignored in designs intended to handle DC voltages, and why impedance is not a function of the length or frequency of a transmission line.
