A simple method of obtaining quasi-continuous frequency spectra of the input impedance of arterial systems

Short Communications and Technical Notes


A simple method is described which permits a complete determination of the input impedance of the arterial system from a single flow and its accompanying pressure pulse. The method is based on the assumption that the pulse under consideration is a non-periodic function and not a periodic one. Thus, an approximation to the Fourier integral permits us to obtain a quasi-continuous frequency spectrum instead of the non-continuous spectrum provided by the usual Fourier analysis of natural pulses.
