Abstract
Having a piecewise linear fitting of gain, one can obtain a good approximation of phase. There are few ways to determine the slopes of a broken line approximation, but the most popular approaches need the breakpoints. In this paper we determine the breakpoints using a divide and conquer approach. Results of piecewise linear approximation of gain and of the resulting phase approximation are provided for different cases.
