摘要
探讨了常系数微分方程与系统的仿真框图之间的互相转换,通过引入中间辅助函数的方法,可使转换过程比传统方法大大简化.对两个不同幅值和脉宽的矩形信号的卷积问题,给出了三种不同的求解方法,并讨论了其各自的优越性和适用范围.
This paper presents an intermediate auxiliary function,which can make the transformation between constant coefficient differential equation and system simulation block diagram greatly simplifier than the conventional method.Then the convolution of two rectangular signals with different amplitude and pulse width is introduced and three different methods are provided and their respective advantages and applications are discussed.
