Signals and Systems - 2 | 线性时不变系统LTI thelittlelamb SJTU 2020Linear Time-Invariant System LTI系统简单:如果我们知道了LTI系统的一个x(t)对应的y(t),就知道了所有的x(t)对应的y(t) 离散系统 δ[n]→h[n],单位脉冲序列→单位脉冲响应 只要知道h[n],即知道∀x[n]→y[n],h[n]是LTI系统...
参考:《信号与系统, Signals and Systems》第二版,奥本海姆著,刘树棠译用脉冲表示离散时间信号如何把任何离散时间信号看成是由 离散时间单位脉冲构成的关键是:要把一个离散时间信号当作一串单个的脉冲来想象。…

LTI systems are defined on a signal space, which is a vector space, closed with respect to a shift operation. Signals are not necessarily bounded and need not belong to a normed vector space. Vector space concepts like dependent and independent vectors are transferred to signal spaces in order...
