I believe you know, but X is active if A1A0 is greater than B1B0, else if B1B0 is greater than A1A0 Z is active, else Y is active. I am not sure if it's allowed to use more than one 2 to 4 decoder, but anyway i want to know how can i do it with one 2 to 4 decoder, and yes i can use standard logic gates.What are X, Y, and Z?
I can guess, but engineering isn't about guessing.
Define your inputs and outputs.
If you can use standard logic gates, then you can do anything because anything (logic-wise) can be done with standard logic gates. If you need more 2-to-4 decoders, make them out of standard logic gates.
You need to be more specific on what the constraints are on your design.
Okay. So now do the other two. Since you can use all the standard logic gates you want, you can do anything you want with the decoder. Tie its inputs LO and then use AND the output that is HI with one of the one of the other signals (which means that it won't change the other signal). As you've described things, that meets the requirements of the assignment.Actually i wrote A1 instead of A0 in the first term, it was typing mistake. I think that rest of it should be correct.
