Factors producing an effect on estimation of the instantaneous analytical signal frequency determined according to the proposed algorithm is analyzed using harmonic quadrature signals as an example. It is shown that joint effect of several factors can lead to substantial deviations of the instantaneous frequency from its nominal value. However, the frequency averaged over a period is equal to the nominal one. This opens considerable promise for using the algorithm to measure the instantaneous velocity and other movement parameters.
