ANALYSIS OF THE IRREGULARLY SAMPLED SIGNALS ABOVE THE NYQUIST LIMIT
Journal Title: Metrology and Measurement Systems - Year 2006, Vol 13, Issue 3
Abstract
A new method of spectrum analysis of the nonuniformly sampled data above the Nyquist limit is proposed, which is based on the digital spectral shift to the baseband, optional filtering and the subsequent spectrum analysis below the Nyquist limit. The method is distinguished by low aliasing frequency estimation and sufficient computation effectiveness. The mathematical background is shown and simulation results are presented to illustrate the method basics.
