How to design a counter for sequence inputs

000 - 001 - 011 - 101

please specify the steps....

 

[Russlk]

This is a 4 bit binary counter.

 

[Dean Huster]

0,1,3,5 isn't exactly binary ....

 

[panic mode]

...and it's 4-step but not 4-bit
you can use any counter and encode states to what ever you want
how many states are there in total? if it's 3-bit code with zero and odd numbers there would be one more state (7 or 111b).

first you should choose a kind of filp-floop
for this case u need three flip-floop .
then u sould make a chart that show each case.like this
Qa Qb Qc A B C
0 0 0 0 0 1
0 0 1 0 1 1
0 1 1 1 0 1
1 0 1 0 0 0
Qa,Qb,Qc are the out put of flip flops in last clock pulse and A,B,C are the flip-flops new out put .then reffering to char u select the flip flop input then use Karno chart to simlyfy it and at the end use the gates to desine circute. I will Send u the circute and charts in few hours.

The circuit u need is this one:

For any help just let me know

I would think a data selector would work.
