| Abstract: | This paper presents the method of analysis of linear circuit by using dynamic signal analyzer.First,frequencyresponse function figure(Bode figure)is obtainad by using the instrument and resonent frequency and half-peakwidth can be distinguished from the figure.Then the parameter of determinet response function can be calculated(for example,damping coefficint,natural frequency,etc).Under the circumstance of not establishing and findinga solution of network equation,response function can be written out and response nature can be determined accord-ing to the form of key.This method is characterized by accurate and swift result and measuring parameter to beeasily distinguished. |
