A charge coupled device transversal filter having split electrodes each having a sense portion and a complementary dummy portion. All electrode sense portions are coupled to a single sense line and all dummy portions are connected to a reference voltage. Tap weights are determined by relative lengths of successive sense portions and weighted samples are taken by shifting charge packets from one sense electrode position to a second while sensing the difference in displacement charge induced in successive sense electrodes. The structure is less sensitive to manufacturing tolerances than earlier structures and provides a sense signal with essentially no common mode component to a sense amplifier.
