通过测量一个系统所获得的信息可以看作是有输入时黑盒给出的响应。在这项研究中，估计有限长度的未知输入波形从一个给定的输入波形响应的二阶阻尼振荡系统进行。通过MATLAB仿真验证了理论分析的正确性。通过实验验证了该理论在真实的系统中的有效性。未知输入波形的估计如下。根据系统的响应波形估计脉冲响应。然后，对脉冲响应的响应波形和估计波形进行傅立叶变换，并且响应波形的频谱由估计的脉冲响应的频谱决定。最后对该结果进行了逆傅里叶变换。所获得的该最终结果是未知输入波形的估计波形。本实验采用激光位移传感器测量了系统的输出波形。结果受到噪声的影响，但是能够估计输入波形
The information obtained by measuring a system can be regarded as a response given by the Black Box when there is an input. In this study, estimation of the finite-length unknown input waveform from a given input waveform response in a second order damped oscillation system is conducted. The theory is shown and verified with the simulation on MATLAB. While the effectiveness of this theory in the real system is shown by carrying out an experiment. The unknown input waveform form is estimated as followed. The impulse response is estimated from the response waveform of the system. Then, Fourier transformation for the response waveform and the estimation waveform of the impulse response was conducted, and the spectrum of the response wave was decided by the spectrum of the estimated impulse response. Lastly, inverse Fourier transform was conducted to this result. This end result obtained is the estimated waveform of the unknown input waveform. In this experiment, the output waveform of the system was measured with an laser displacement sensor. The result was influenced by the noise, however the input waveform was able to be estimated
