摘　　要：从理论上严格证明线性时不变系统时域分析的核心是卷积,卷积不仅能计算系统冲激响应和零状态响应,也能计算系统零输入响应和全响应.Convolution technique applied to analyzing a linear time-invariant system （LTIVS）in time domain is discussed in this paper. It is shown that the kernel of characteristic analysis of all LTIVS in time domain is to compute the convolution of its input excitation w;th me system＇s impulse response. It is proved that convolution can be able to be utilized to analyze the zero-input response and total response of a LTIVS as well as its impulse response and zero-state response.

关 键 词：信号与系统 线性时不变系统 时域分析 零输入响应 零状态响应 全响应
