Hi I am little stuck on coursework I could use help or direction to other learning sites to read about this kind of project. I chose to use JK-flip flops and planned following structure diagram: https://i.imgur.com/9hNAMgu.png. I made it quickly on computer but idea is that it keeps looping odds or evens depending on input and when input changes it round up to closes odd/even number and continues the other loop. I also did transition table on excel https://i.imgur.com/30Xg209.png I know next I'm supposed to make Karnaugh's map, but I can't get even started because we have never discussed 4 bit counters during lectures, maximum I have received teaching for is 2 bit counter. I saw similar(ish) kinda build in here http://www.doc.ic.ac.uk/~dfg/hardware/HardwareLecture08.pdf using D-type flip flops, but it still only uses 3 bits. Thanks in advance. I hope you can help me.
