Hi everyone:
I'm stuck on this problem. Here are the directions:
An electronic game uses an array of seven LEDs to display the results of a random roll of a dice. A decoder is to be designed to illuminate the appropriate diodes for the display of each of the six die values. The values are 1 through 6, each on a different die.
a) Use a 3 to 8 line decoder and OR gates to map the 3 bit combinations on inputs X2,X1,andX0 for values 1 through 6 to the outputs a through 6. Input combinations 000 and 111 are don't cares.
I am really stuck at how go on this one. I set up a 3 to 8 line decoder but can't get past that. I have all of the numbers, 1 through 6, converted into xyz form (expressing them in forms of X,X',Y,Y',Z,and Z') but don't know how to put them in as inputs to the decoder or how I am supposed to use OR gates at all.
Thanks for your help/solutions!!
