Hi,

I am looking for someone to review my answer to the following question:

"Using K-Maps design FSM that can implement a 4 bit counter. Show all steps of the design process. The counter must count from 0000 to 111. Label counter outputs Q3,Q2,Q1 and Q0."

So I have finished the K maps and they are below... How am I doing? Thanks

 

Your K-maps are correct. You just forgot to fill the 4th product in the last function.

When I construct 4-variable K-maps I usually sort the ABCD variables like so: http://www.allaboutcircuits.com/vol_4/chpt_8/7.html

 

Sorry for the late reply..
Thanks for the help.

They way I do the karnaugh maps is the way I have been taught..
