Abstract
The comparison of three different algorithms
for the estimation of parameters of two sine signals with
common frequency is presented. The algorithms are the
ellipse fit, the seven parameter sine fit and the spectral sinc
fit. The comparison includes signal to noise ratio analysis,
amplitude analysis and phase difference analysis.
