| Abstract: | The dynamic theory by which a conventional electrocardiograph can tracing ECG with high fidelity is present by applying automatic control theory and the author's research result on stability theory of multistage feedback amplifiers. The dynamic characteristics of main amplifier is analysed. The stability criteria and the stability margin of amplifiers are given. Moreover, regulations for dynamic design of conventional electrocardiographs and the calculation methods for dynamic parameters are suggested. The conclusion given in this paper is consistent with the debugging results of several products. |
