assignment: design a counter through all the odd numbers from 0 - 15.

progress: i think i have everything correct.

can someone verify for me? i'd appreciate if you could point out any mistakes.

i've attached what i have so far. thanks in advance for any help.

 

Did you notice that Q1, Q2, and Q3 are a standard binary counter, and Q0 is always =1?
It seems to me that you only need 3 FFs.

 

Or, if you have the option, use a standard counter IC. Take the 3 MSBs and use a HIGH pin to generate the LSB.

I was hoping he would figure that out from my post.

 

To be honest, I didn't think of an IC counter when I read your post, but of a discrete Flip Flop counter.

Yeah, I didn't read your post carefully enough. I was in fact thinking he could design a 3 bit counter from "scratch", scratch being JKs and maybe some gates. I didn't consider that he could use an IC binary counter, and, seeing that it was homework, I'd be willing to bet that I'm right about that.
