Abstract
The dual edge and level (DEL) flip-flop not only is sensitive to both posve and negative edges and level inputs, but the device can be made sensitive to (1) positive edges only, (2) negative edges only, (3) both positive and negative edges, or (4) neither positive or negative edges. In any case, the output can be controlled by the level inputs which override the edge operation.
