COMPARATIVE ANALYSIS OF CHARACTERISTICS OF COMPLEX AND ANALYTICAL SIGNALS
Annotation
A comparative analysis of accuracy of amplitude and phase measurements for complex and analytical signals is carried out. It is shown that retrieving of analytical signal with the use of the Gilbert transform, introduces errors when quadrature component is derived. Relative errors of measured amplitude and phase values are calculated in a wide range of values of the ratio the average frequency to the width of the signal spectral density, for the cases of amplitude and phase modulation of carrying oscillation.
