fig. 13. The resonant network model of the arterial system. Component values indicated are those 

 found in one typical experiment on an anesthetized open-chest dog. 



fig. 14. Experimental testing of the resonant network model of the arterial system. Pi = pressure 

 in the aortic arch. Pi = pressure in the femoral artery. F = flow in the ascending aorta. l\ = the 

 voltage across the capacitor- C, to ground. V« = the voltage across the capacitor Ci to ground. In 

 the first panel the values of G and Co have been adjusted to give the correct resonant frequency as 

 represented in the arterial pulses. Between the first and second panels, R 4 was adjusted to give the 

 proper damping ratio of the series resonant elements C\ , C« , and L. The third panel shows the 

 closest equivalent achieved by adjusting R :i to reduplicate in Vi the high components of P l . Delay in 

 transmission time is not present because the simplicity of the analogue limited the number of L-C-R 

 transmission line segments.
