It will introduce the responses of the step, ramp and impulseinput for mechanical and circuit systems by using Laplace transform.
本课程将介绍机械与电路等系统的模式，利用拉氏转换决定步阶，斜坡及脉冲等输入的响应。

The nonlinear gain and the impulse response functions of linear subsystem be obtained by using the step-changeds and cyclic impulse with different amplitudes as input signals.
In this paper, a method of measuring the input mechanical impedance of the array element (longitudinal vibrating transducer) with square radiation head by using impulse sound tube is proposed.
