冲激函数及其特性解析

Parsing on Impulse Function and Its Essential Character

本文运用类比分析和逻辑推理及计算机仿真的方法,对冲激函数的本质特性进行了分析和解释,给出了冲激函数是一种理想的信号模型和试验信号,也是一种类扫频信号的观点。这一观点有助于读者理解在信号与系统分析中引入冲激函数的目的与意义,以及冲激响应与系统函数的物理意义。

The essential character istics of impulse function have been analyzed and explained by using analogism method and computer simulation. The impulse function is an ideal signal models and allied frequency scanning signal, it is also a test signal, this viewpoint is helpful for the readers to understand the intention and meaning of introducing impulse function, also helpful to apprehending the exact physical meaning of impulse response and system function exactly in signal and system analysis.
