i have been given a assignment i have to produce an overall truth table for the 7 segment display covering the 16 possible inputs and outputs for all 7 segments. That bit was easy now i am doing the proof table not having much look can anyone help?

Is this a programming problem or just a general question?

[numerical_jerome]

a 7-seg display would have 128 different "possible inputs". Do you mean the 16 characters that would be used to display Hexidecimal?

i have sorted it its all good it was simple

What's a proof table??

Would you be willing to post how you solved this problem and maybe a little more details about it.


Just for the simple fact that it could benifit someone else in the future.

okay, if there's anyone out there wondering about the solution...
a 7 segment display is something like this :

as you can see, there are 7 lines, 7 outputs. each output will be showing whether the corresponding line will appear or not.

so, for those value, write a truth table.

create their k-maps, and consequently their designs.

there you go!
