Although the emphasis of this book chapter is on frequency-dependent network equivalents, the same identification techniques are applicable to the models of individual components. For example, a frequency-dependent transmission line (or cable) equivalent can be obtained by fitting an appropriate model to the frequency response of its characteristic admittance and propagation constant.
