Can anyone send me a 4-bit binary divider circuit in this email : kkaranasos@in.gr ? I must make this homework for my university and i am late. I have to make this circuit only with NAND gates. PLEASE HELP !!!!!!!!! Thanks a lot

I draw the line when the student submits nothing to show that he/she has even tried to do the work. The purpose of school is not to turn in someone else's work--what do you learn from that? I also have to question the utility of assigning such a problem. I think the professor is out of touch with reality or is a sadist. Also, without considerable research, I cannot design such a counter using only NAND gates--not that I would want to. Charles

Sheeeesh! I'm an analog designer and I can. Ever heard of master-slave.

If your homework is too tough, and the time just flies away, thinking hard is not enough, click: comp.arch.fpga. There you find those friendly souls, Austin, Philip, Peter, Ray filling in your knowledge holes, making problems go away. But learning is for you to do, even if it hurts the brain. The one that has to learn is you. There is no substitute for pain. If you want to learn design don't treat homework just as play. Real life is not benign, and you'll have to earn your pay! sooner or later...

More constructively, your professor wants you to: 1. realize that you need four cascaded flip-flops, 2. then "re-invent" the master/slave flip-flop, which you can also find in old TTL databooks (7474). Maybe an interesting learning experience, kind of like the boy-scout test of starting a fire without matches... Have fun !

Potassium Permanganate and glycerine which spontaneously combusts and gets hot enough to light the Magnesium, which is hot enough to light the thermite. I thought it was impressive.

But it could be an arithmetic divider. Just thought I'd point that out. Mac
