A filter is applied between a digital signal source and a signal receiver for providing compensation of droop caused in a transmission path between the signal source and the signal receiver. The filter provides a high pass characteristic substantially approximating or following in a relevant frequency range an attenuation function substantially proportional to e-k{square root}{square root over (f or-when denoting attenuation in dB-substantially proportional to the square root of the frequency.
