An equalizer introduces into the attenuation versus frequency curve of a signal carrier transmission system compensatory bumps of adjustable magnitude and of adjustable frequency location. When the bumps are in their initial frequency locations, they exhibit the following features: (a) The middle frequencies of the bumps are each shiftable with respect to frequency by an amount equal to at least one half the frequency interval to the respective neighboring bump. (b) Adjoining bumps of equal magnitude have facing flanks which overlap and intersect at a point which is at least 0.6 of the way up the height of the bump. (c) The middle frequencies of the individual bumps are distributed within the frequency range to be equalized in at least approximate correspondence to the detail density distribution function d*. The function d* is a novel function defined herein.
