【摘要】 本文系统的提出了如何把《信号与系统》从一门由数学语言描述的"理论课"和具体应用联系起来,通过把大量的知识点组成一个个知识群,每一个知识群都由一系列具体的硬件电路或计算机程序支撑,详细说明《信号与系统》的"数学理论知识"究竟怎么用,从而把《信号与系统》从一门理论课程变成了一门应用课程。更多还原

【Abstract】 Signal and System is described in a mathematical language is quite confusing for many students. In this paper, the mathematical formulation is related to practical applications, such as analogue circuits for analogue filters and computer programmes for digital filters. We assort the whole Signal and System into many knowledge groups and each group is supported by some application examples. So, Signal and System has become a course of application and it is not a pure theory anymore.更多还原
