Design a counter using JK flip flops
Hello I am doing the grade 11 computer engeneering course and I was doing my homework when I got stuck on a question that says "Design a counter using J-K flip flops that will count in the following sequence: 0,2,5,1,3" would some one please help a newbie like my self make this counter. I have been trying for hours and still dont know how to do it.
Thanks any help is apperciated
EDIT: beenthere first we have to create a truth table (I did that)
Q2 Q1 Q0 Q2 Q1 Q0
0 0 0 0 1 0
0 1 0 1 0 1
1 0 1 0 0 1
0 0 1 0 1 1
1 1 1 0 0 0
then we had 2 draw truth tables did that too.
but then we have to make the truth tables into a diagram thats were Im getting stuck...this is what the diagram looks like:
____________ __________ ___________
|J2 Q2 | |J1 Q1| |J0 Q0|
| | | | | |
O>CLK | O>CLK | O>CLK |
| _ | | _ | | _ |
| K2 Q2| |K1 Q1 | |K0 Q0 |
--------------- ------------- -------------
(I know its a bit rough but you get the idea..I hope)

Get the data sheets for those chips - you might be surprised to see what they are. Google "sn7490", sn7492, sn7493" and follow the links for the data sheets.
First comes the hardware, then the software.
