Don't Cares and the 7 Segment Display

How the seven segment display works and how to use a Karnaugh map to determine the simplified Boolean function for each output using Don't Cares. From the Digital Design course.

Thank you so much for this explanation! My prof didn't transition to online classes very well and it has made the learning process much more difficult but this video definitely helped.

Two things - the last grouping could ditch the Y, as you can group 4 corners, rather than two cells. Another thing is regarding the 6 and the 9 - in those you can have "A" and "D" outputs as don't cares, respectively, and see which form is easier to implement during simplification. Otherwise - great video! Deserved rounding up the likes to 64 :D

Omg this solves everything for me

[@jbergamp]

I got lost...why did you get the column and not the first row to put into k map to express "0" ??

[@1zhann184]

the orange group could include all 4 corners coudlnt it?

[@muhammadtalal7004]

Yes I also think so

[@DMES-wp2fj]

not an expert but you're right however what she did is still right

[@DwarfInBlues]

Yep, could discard the "Y" from there.
