在线性系统的设计与综合中,往往需要了解被测系统的传递函数.本文讨论了利用最小二乘法进行传递函数曲线拟合的方法,并给出了实用拟合程序及拟合实例.
In the design and synthesis of linear systems, it is often necessary to know the transfer function of the system under test.This paper discusses the method of curve fitting transfer function using the least square method, and presents practical fitting programs and fitting examples.
