    It will help if you indicate the values for A, B, C, & D. E.g.,

    Code ( (Unknown Language)):
    1.  
    2. [FONT="Courier New"]
    3. \ A 0 1 1 0
    4.  \B 0 0 1 1
    5. [U]CD[/U]\_________
    6. 00|
    7. 01|
    8. 11|
    9. [U]10[/U]|_________
    10. [/FONT]
    11.  
    This way you (and we) can see if you are correct more easily.

    hello shinn90,
    since there are no octets we go for quads and you can add the minterms
    already included in a group to a new group
    so we get
    DC' + B'A + D'C + B'D' + D'A
