摘　　要：在RC电路中,采用单脉冲近似冲激激励和强迫跃变、以微分信号为冲激激励和用RC微分电路对阶跃响应进行微分3种方法对冲激响应进行研究,对所测量的各响应波形进行理论分析以判断是否为冲激响应,并提出得到冲激响应的近似方法。介绍了这一创新的研究性自主性实验的实验设计思想。The aim is to introduce the experimental design of the a novel independent research experiment regarding the investigation of impulse response. Three different methods （i. e. , single pulse approximate impulse excitation and forced jumping, impulse excitation with the differential signal, and differentiating the step response with RC differential circuit） are preformed to experimentally investigate the impulse response. Then, theoretical analyses on the measured response waveforms are carried to verify the impulse response. Finally, the approximate method to achieve the impulse response is put forward.
