The columns of the state table shaded in tan produce the map for q1 and the gray columns on the truth table produce the map for q2 . A word of caution is in order (although it does not come into play in this problem). The state table has the present state numbered in binary order; the map, of course, has them numbered appropriately. The last two rows of the state table must be interchanged when they are copied onto the map. (Some people prefer to draw the state table in map order to avoid this problem, that is, 00, 01, 11, 10; that also works.)
