Interpolator eliminates the spectrum alliasing effect and ,therefore, allows to measure correctly blood velocities beyond the Nyquist limit. Investigations were performed with Doppler signals, having spectrum of various form. The distortions of the signal spectrum reconstruction were analysed.</span>}, number={4}, journal={Elektronika ir Elektrotechnika}, author={Kopustinskas, A. and Kitkauskaite, A.}, year={1997}, month={Nov.} }
