Abstract

This article is devoted to the investigation of boundary working capacity conditions of 1st order software PLL. The principle of operation of the PLL in static mode has been considered and an expression for calculating the PLL hold range has been deduced. The paper presents experimentally obtained dynamics of phase synchronization error over time for different initial conditions as well as the PLL hold range for a number of values of VCO center frequency and cutoff frequency of broadband filter.
