Hi,
I need help with writing a state table of 7 segment with 4-bit input A,B, C "Present state", and x "Input".

What does this have to do with flip-flops. Binary to 7 segment is a combinatorial problem, so no state table. Right? I think we need a better description of what you have in mind. A schematic diagram would be great for that purpose.Hi,

Because we need it to work with 1 Hz frequency. Thus, yourWhat does this have to do with flip-flops. Binary to 7 segment is a combinatorial problem, so no state table. Right? I think we need a better description of what you have in mind. A schematic diagram would be great for that purpose.
Since this is Homework, post your best effort at solving the problem, so that we can give guidance where needed.
It should be 3 inputs (A, B, C).Since this is Homework, post your best effort at solving the problem, so that we can give guidance where needed.
I don't have a very clear picture of what you are describing. With each answer you reveal additional details, but not the complete picture. If you don't have a schematic diagram how about a simple block diagram of what you have in mind, because your words are just not making it clear.Because we need it to work with 1 Hz frequency. Thus, your
counter will count once per second.
This is different than what you initially posted. Please post the entire text of the problem and the due date.It should be 3 inputs (A, B, C).
And Output should be in this sequence ( 5-3-7-1-0-4)
I really appreciate your replies and your need to help.It appears that you checked your thread and didn't feel like answering any questions. I'll tell you that your table has an error.
The don't cares are fine as long as the problem didn't give some requirement for how quickly the circuit needed to count out of invalid states. For homework problems, invalid counts are typically treated as don't cares to facilitate simplifying the logic.
In addition to not using 'A' for the LSB, are they not teaching you to put your truth table in gray code order? Using gray code that facilitates transferring data to Kmaps.
Also note that the transition table (I think that's what they call it) for D flip flops is the same as next state.
The way homework help works on AAC is you have to do most of the work and we're only allowed to give you hints. That means urgent requests are doomed to fail.But, the deadline was yesterday and we got other things to submit with this homework, so me and my team was so busy and stressed to meet the deadline.
