The invention relates to a network for correcting a circuit for slaving active magnetic levels receiving an input signal Ve and delivering an output signal Vs, including means (20, 30) for differentiating the input signal Ve, in a defined frequency band in the vicinity of the characteristic frequency of the slaving, the implementation of these differentiating means being conditioned by the operation of peak-limiting means (300) the action of which is controlled by the input signal crossing a predetermined threshold voltage Vthreshold, the output signal Vs reproducing the input signal Ve when this threshold voltage is not reached. More particularly, the differentiation means include a second impedance circuit (30) arranged in the feedback circuit of an amplifier (10), the input signal of which is differentiated by a first impedance circuit (20), the second impedance circuit including, in parallel, the peak-limiting means (300) and an impedance circuit (200) identical to the first impedance circuit (20) so that, in the absence of a crossing of the predetermined threshold, the peak limiting circuit remaining inactive, the differentiation of the input signal is not carried out and the output signal Vs remains identical to the input signal Ve. <IMAGE>
