ABSTRACT OF THE DISCLOSURE A filter in the form of a semiconductor charge coupled device (CCD) split electrode transversal filter section (10) of many transfer stages, typically of the order of 150, is characterized by a controllable detection threshold level by means of the addition of an auxiliary CCD split-electrode section (20) of but a few stagers, typically one or two. Each segment of a split- electrode 209 of this auxiliary section (20) is connected to the corresponding sense line of the transversal filter section (10).
