    Let's make sure we understand what you are asking for.

    You have an assignment that you are supposed to complete, but you have no idea how to do it and can't even explain it.

    But you DO have a completed project from a friend in which the only difference is the ID number that needs to be used.

    But you can't understand your friend's work well enough to figure out what needs to be changed.

    So you want strangers to do your work for you without and don't believe you should be expected to put in any effort at all or understand the solution you plan to submit and claim credit for.

    Would you feel comfortable going to a doctor that got through medical school taking the approach you are trying to take?

    Do you have a link to the course website so that we can see exactly what the problem is?

    Most of us are not disposed to do that for you. This is Homework Help, not homework done for you. You can show us what you have done so far and we may or may not be able to guide you further. That's as good as it gets. If that is unacceptable to you, then I don't know what to tell you. Maybe some bored soul will derive joy from giving you a bogus answer, which you will turn in, and get a failing grade. At least I won't go that far.

    I'm not mad at you, and I didn't use uppercase letters, which many consider to be the equivalent of yelling. I'm a strictly dispassionate observer trying to make you aware of certain unpleasant (for you) realities. You can shoot the messenger if you like, I don't care, but it still won't help you find what you are seeking. What people will respond to is a sincere effort on your part to solve the problem for yourself and show us how you think it should look. Do that, and I forsee a wave of helpful comments. Ultimately it is your choice on how to proceed.

    P.S. The use of the word "Urgent' in the title is a dead giveaway about the nature of your question.

    Hi,

    Please read this post. This is from that post:
    Where are your attempts?

    Note the second paragraph. "Give your posting a descriptive title."

    If you do that, I'll bet you'll get all the help and guidance you need to get the 20%.

    You do realize that many professors may have accounts here and are watching for students trying to take shortcuts. It baffles me why you would want to risk your tuition money and your reputation to avoid an investment of time and effort on your part.

    In other words, you are concerned that someone might inform your school that you are cheating.

    If you want help, post your work (start with truth tables and Kmaps) and someone will attempt to guide you to a solution.

    If you're asking for someone to simply do the work for you, as others have noted, that isn't going to happen unless some member goes against the intent of the Homework Help forum.
    From the images you posted, it seems like the problem is an Excess-3 converter to a 7 segment display. Break it down into two problems; that's the way most would do it. Also specify which bits are MSB and LSB. The work you posted seems to be backwards from the usual convention.

    EDIT: Actually, I can't tell what it is from the images...
    Is the solution supposed to be general (e.g. work for all numbers) or just a solution for the numbers in your ID?

    Why solve two problems when you can solve just one? Unless the actual assignment is to solve two problems, one could put the BCD ID numbers directly into a seven-segment decoder for Excess-3 display (while taking advantage of the fact that numbers not in the ID won't need to be displayed). Can we assume that student ID digits greater than 6 should be displayed as hexadecimal numbers in Excess-3 code?

    Because that's what was being done in the work posted from other students and the way another student with a similar question was solving it??

    Redon, do you need to make a BCD to x53 converter as the first step in this assignment. From the posted work, I can't tell if that is required or not. One step at a time, please answer that first.

    Anyone know why colleges seem to want to teach excess-3 codes so often? I know why they were important in the fifties and sixties, but there's really no need now. I think it would be more important to teach ASCII, maybe EBCDIC, and newer expanded character codes. Maybe that comes later.
