Line equaliser for compensation of droop effect

摘要

A filter (10) is applied between a digital signal source (20) and a signal receiver for providing compensation of droop caused in a transmission path (30) between the signal source (20) 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><SQRT>f</SQRT> or - when denoting attenuation in dB - substantially proportional to the square root of the frequency. <IMAGE>
