Summary/Abstract: The wave signal of electronic sphygmomanometer, recorded in personal computer provides whole information for the wave character of the artery blood flow. The corresponding function can be processed by discrete Fourier transformation described by a mathematic method in the paper. The algorithm consists of reducing the digital function to an acceptable size, discrete Fourier transformation and its graphic presentation. The frequency response covers wide range of the human spectrum and bears specific wave picks at given human frequency components. On their base, a general issue is formulated and suggested.
