A digital tracking phase meter comprising a shaper of narrow pulses corresponding to a leading edge of an input square-shaped signal, connected by the output thereof to one input of a switch, the other input of which is applied to a data output of a phase cycle fraction reversible counter, and the output of which is connected to an input of a pulse counter. A countdown input of said pulse counter is connected to a count pulse generator, and the output thereof is connected to an input of a control pulse distributor switch. The other input of said switch is connected to an input of a control pulse distributor inverter and serves as an input of the digital tracking phase meter, whereas the output thereof is connected to a countup input of said phase cycle fraction reversible counter. An output of said inverter is connected to an input of another control pulse distributor switch, the other input of which is connected to an output of said pulse counter and the output of which is connected to a countdown input of said phase cycle fraction reversible counter. Outputs of said reversible counter are connected to countup and countdown outputs of a phase cycle integer reversible counter.
