从信号分解的观点来分析线性系统,则无论是时域分析法还是频域分析法均可看成为某种特殊函数的响应方法。与脉冲函数响应法和阶跃函数响应法相比较,在作者提出的门函数响应法中,由于输入函数分解得出的基本信号分量相互不存在时间延迟,线性系统的零状态响应可表示为一般积分形式,从而简化了计算。 Analyzing the linear system from the point of view of signal decomposition, both the time domain analysis and the frequency domain analysis can be regarded as the response method of some special function. Compared with the pulse function response method and the step function response method, in the door function response method proposed by the author, since the basic signal components derived from the input function decomposition have no time delay, the zero state response of the linear system can be expressed as a general integral Form, thus simplifying the calculation.
