Abstract: In this paper, the least squares approximation via a piecewise linear function approach is applied to solve the approximation problem of a sum of lognormal random variables. A number of ...

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 ...
