摘要
介绍用数学方法推导出二阶系统信号恢复的计算方法 ,并用算法语言在计算机上模拟出当其输入信号为标准半正弦波时的输出信号 ,以及当输出信号为计算出的信号时模拟恢复出原输入信号 ,并讨论了在该算法的数学推导及模拟实验的基础上恢复动态信号的可能性。
In this paper,the calculating method of the second order system signal recovery has been derived by mathematical approach.The output signal is simulated by ALGOL on computer when the input signal is a standard half\|sine wave.The orignal signal of the system is recovered through calculation when the output signal is this calculated signal itself.Based on mathematical derivation of this algorithm and simulative experiment the possibility of recovering the danymic signal is discussed.
