摘　　要：求解线性时不变系统的全响应是"信号与系统"课程教学中一个重要知识点。本文总结了仅已知系统非因果输入、系统初始条件未知情况下,分别从时域、频域和复频域,直接求解线性时不变系统全响应的三类主要方法。我们对这三类方法进行了总结和对比,并以实例说明其正确性。Solving all response of LTI system is very important for signal and system course.Three types of methods for directly solving all response of LTI system from time-domain,frequency-domain and complex frequency-domain when non-causal input signal is given but initial condition is unknown are summarized in detail.In order to indicate that the three methods are unified,summarization and comparison are made.
