Please help a student :) ->BCD to 7-segment


i have a question and i hope that you could provide an answer.

i got an assigment which goes like this:

draw and explain : BCD decoder to 7-segment code/display with a decoder and OR function/gate. on the link at the and i found what looks to be the solution to my problem but their is another problem. how do i get the logical function from the truth-table? the author says that i should minimaze the function using K-tables for every output but i don't know what to put in the K-table. can somebody do one example so that i can see what am i suposed to do? i'm guesing that i should then connect the output to the OR.

There really is enough info in that link for you to do this assignment. You can also look elsewhere, you found this one and the author suggests some references.
