Abstract

Despite the large number of publications on digital signal processing in systems of different appointment, up to date, when choosing the sample frequency of recorded oscillations, their authors refer to the Nyquist’s theorem (sampling theorem). This theorem is connected with the transform of the continuous signal in the sequence of its discrete values. It is assumed that the signal will be transmitted through the band-limited communication channel. However, until now the question of the impact of the frequency on the efficiency of the further digital processing remains open.
The article studies the influence of the sample frequency on the efficiency of the digital signal processing applying the method of simulation. The research was performed on the example of formation of the quadrature component of the analytical signal by means of Hilbert and Hilbert-Huang transforms. For the first time we have assessed the quality of the formation of the quadrature component, depending on the sample frequency at various signal/ noise ratios. These results can be used in radio, radar, acoustic and seismic systems of different appointment.
