    I need a solution to this problem question so i can understand it. I suspect the solution makes use of XOR. The figure is just 7 segments making an 8 symbol.

    Write down which LEDs you want to light for each segment, make a truth table and then use SOP or POS to make the circuit. If you want use K-maps or other methods to simplify the circuit.

    As mik3 has pointed out, you can organize your attack on this problem using a truth table together with sum-of-products (SOP) and product-of-sums (POS). Here is a link to some material in the AAC ebook that would be good to review along with other chapters in the Digital Section of the ebook.

    Take a stab at the truth table and then post your effort here. Our members can then assist you.
