Abstract :
The paper presents the analysis of the amplitude absolute error of a digital sinewave generator with step approximation and step-linear approximation. Further in the paper is presented an investigation of the spectrum of digital sinewave generator signal. Non-linear distortion (NLD) of digital sinewave with step and step-linear approximation is analysed. The non-linear distortion is calculated in order find the approximation with smaller NLD. Up to this paper is made cooperative analysis of the amplitude absolute error of digital sinewive generator with linear approximation and step-linear approximation.
