摘要：

One of the oldest and most useful techniques available in network theory states that the phase can be approximated using the slope of the logarithmic gain characteristic. The goal of this paper is to present some results concerning the analytical properties of logarithmic gain. We also show that a better phase approximation can be obtained in certain situations if the third derivative is taken into account.
