Abstract
In this report the errors of the measurement phase shift between the harmonic signals using
binary sampling are analyzed. The main source of errors in such measurementі is the inequality of signal
amplitudes. We determined four methods of measuring the phase shift whose we are considering here. The
mathematical models of additive errors for various methods were determined and a their comparative analysis
is carried out. The graphs of dependences of errors on amplitudes inequality are constructed. The method that
provides the least error is determined.
