| Abstract: | With Fourier Series as a tool, we analyzed the flow wave and the pressure wave which were tested at the root of the aorta. A set of hydraulic devices which could produce sine flow were used to simulate the flow wave. Using the Westerhof model as left ventricle afterload we got the pressure wave. This design is relatively accurate and flexible. |
