Analogue filter, in particular for an electronic measuring apparatus such as a balance, in which the analogue measuring signal Ve consists of a continuous component proportional to the magnitude to be measured, on which is superimposed an alternating component due to the disturbances of the environment, characterised in that it comprises a filtering circuit RC followed by an inverting circuit A2 and by an inverting summing circuit A3, the measuring signal Ve being applied simultaneously to the input of the filtering circuit RC and to the input of the inverting summing circuit A3. <IMAGE>
