摘　　要：On the basis of the pulse source-system model, a convenient and effective method used to evaluate the transfer function of human pulse system has been proposed by using the principle of signal detection and system analysis. The experimental results show that the pulse system of the normal pulse has 3 formants; the smooth pulse, 2 formants; the wiry pulse, 4 formants; and the thready pulse, only 1 formant. Formant frequencies reflect the resonance behaviour of the arterial system.On the basis of the pulse source-system model, a convenient and effective method used to evaluate the transfer function of human pulse system has been proposed by using the principle of signal detection and system analysis.
