说明：  基于MATLAB的电路分析 以MATLAB软件为工具，通过几个具体实例介绍了电路分析的方法(MATLAB-based circuit analysis tools in MATLAB software, a few specific examples introduced by the circuit analysis method)

考虑你在哪里不同的传感器，桥上两侧的汽车造成的振动记录收集数据的情况。当你分析这些信号，则可能需要对齐。假设你有3个传感器以相同的采样速率工作，他们是造成同一事件的测量信号。(Consider a situation where you are collecting data different sensors, recording vibrations caused by cars on both sides of a bridge. When you analyze the signals, you may need to align them. Assume you have 3 sensors working at same sampling rates and they are measuring signals caused by the same event.)
