Those pictures are the difference between a latch and a modulator.

.

1) The first picture is a latch. . During an Up cycle, I input 3-1-4-2-4-1-3. . The output remain 3-3-3-3-3-3-3. . Why ?? Because, it is a latch. . The output depends on the feedback. . If I wanna a 3-1-4-2-4-1-3, what should I do?? You should 3-(down cycle)1-(down cycle)4-(down cycle)2-(down cycle)4-(down cycle)1-(down cycle)3

.

2) The second picture is a modulator. . If I input 3-1-4-2-4-1-3, the output is 3-1-4-2-4-1-3. . Why ?? Because, the output is independent from the feeback.

3) The third pictue is clear. . . . If there is a feedback, it is a latch. . If there is no feedback, it is a modulator.
