divide by 3 circuit in state machine

Its not possible.

Hi Man,

You can't implemnt it in anyway.

Thing is that two store a two bit number you requires two Flops.
(00,01,10,00,......or any of your desired combination)

use a state machine of three state.circulate between this three state each clk with high in one or two clk and low in other.so u get divide by 3 clk with 33.3% or 66.6% duty cycle.

Atleast two flip flop is needed to divide by 3 stages.

 

[vikas2502]

yes ofcourse two f/f is required.as it required 3 state.
what i mean to say that we can skip one state out of three

Yes, your circuit would be wired to reset both F/F to their 0/0 state after the 1/0 state. sequence would be:

00,01,10,00,01,10,00........

Actually, i saw divide-3 circuit by one flip-flop once. but i cant remember it now.

I know that the circuit includes one flip-flop and combinational logic. And one of the inputs of combinational logic is clock signal. So it can implement divide-3.

its nt possible becoz ..how do u show two digits with one flop...or may be u can implement flop using combo logic...

 

[quan228228]

but i really really saw the circuit once. if i found i show you.

hey guys ....
i too have seen it somewher ....
it is implemented using 1 FF and some combo logic !!

prolly can reply with the diagram mebbe tmrw ... need to search !!!
