We wish to design a decoder, with three inputs, x, y, z, and eight active high outputs, labeled 0, 1, 2, 3, 4, 5, 6, 7. There is no enable input required. (For example, if xyz = 011, then output 3 would be 1 and all other outputs would be 0.) The only building block is a two-input, four output decoder (with an active high enable).
