As an important class of hybrid dynamical systems, a switched system is composed of several continuous time subsystems or discrete time subsystems and the switching signal among them.

切换动态系统是一类重要的混合动态系统，它是由几个连续时间子系统或离散时间子系统及作用在其中的切换规则构成的。

In the control system of sampling, signal to be dealt with is the pulse sequence after sampling from the continuous time signals.

采样控制系统中，所处理的信号是连续时间信号经采样后所得到的脉冲序列。

The system which is test successfully can analysis the frequency spectrum of input signal and export spectrum of the continuous wave or the information in the frequency-time of the pulse.

该系统能对输入信号的频谱进行分析，实时输出连续波频谱或脉冲波的时域频域信息，并已测试成功。
