Clock frequency division

Hello guys,

I've got two questions as a real beginner.
I've got to make a clock frequency divider by 6 using D Flip Flops. I've read some articles etc. and I managed to 'build' one (using electronic workbench software) by dividing it by 3, and then by 2. Is there any other way to make it work that way? The thing is, I need to put diodes for each state (0-5).

The second question is - how can I achieve duty cycle reduction to 1/3 (from standard 1/2)? Any suggestions?

Thanks in advance.

Have you learned state transistion diagrams?
Have you learned state machines?
Have you learned present state/next state tables?
Hufman?
Mealy?
Moore?

How a D-FF could count up?
How many stages of D-FF should cascaded?
What number the counter should be reset?
What kinds of IC doing with time/timer?

What do you mean by "put diodes for each state"? Are you talking about LEDs?

You need to define precisely what you want the output(s) of your circuit to do. A timing diagram is very useful for this purpose, but a state diagram or state transition table can offer the same information, sometimes better, sometimes not as well depending on the specifics.
