A synchronizing signal separator network for use in an information reproducing system including a time-axis error signal generator, comprising a non-linear impedance circuit to non-linearly modify the amplitude of a supplied composite video signal for suppressing the video signal component of the composite video signal, a differentiating circuit to differentiate the output signal from the non-linear impedance circuit and a slicing circuit to slice off those portions of the output signal from the differentiating circuit which are higher in magnitude than a predetermined level, the output signal from the slicing circuit being used to produce a signal to be compared with a predetermined reference time-axis error signal signal in the time-axis error signal generator.
