7 segment display + logic gates

    1. The problem statement, all variables and given/known data
    I'm tasked with creating a logic network that can spell out a simple 4 letter word. It has 2 inputs A and B, and 7 outputs (for a 7 segment display). The 2 bits (A and B) give the 4 total possible inputs to the circuit.

    Write the truth table for the 7 output functions, minimize them using a K-map, and implement them using logic gates.


    2. Relevant equations



    3. The attempt at a solution

    I've created the truth table.

    But I don't really understand how I am supposed to use K-maps to simplify this.
    Am I supposed to create 7 functions, for example:
    C1 = A'B' + A'B +AB
    C2 = A'B' + A'B
    C3 = A'B'
    ... and so on, up to the seventh.

    Then use the Kmap to minimize those functions?

    Do post your solution besause it looks like it should simplify quite a lot.
