接下来介绍稍复杂一点的单位阶跃(unit step)序列 u[n] ,定义为: u[n] = \begin{cases} 1 , & n \ge 0 \\ 0, & n < 0 \end{cases} \\ \tag{2} 对应的图形为: 图3:单位阶跃序列 我们尝试用最简单的 \delta[n] 通过信号运算来得到稍复杂一点的 u[n] 。回顾一下,到目前为止,我们掌握的...
在本讲中，我们将深入探讨信号与系统领域中的两个基本概念：单位脉冲与单位阶跃函数。这些概念在实际应用中尤为重要，帮助我们理解系统性能并进行测试。以买西瓜为例，通过敲击来判断西瓜的成熟度，实际上是应用了单位脉冲信号的思想。在乐器店，用锣或鼓的击打声来评估乐器质量，这一行为同样体现了单位脉...
