Hi Guys!
I had to do a logic circuit to solve Y=3X. Below is the truth table.
To simplify the truth table a little bit I created the one below.... Lets focus on this one!
I couldn't find any info on how to solve this truth table. I know how to use minterms and maxterms for truth tables with single output, but I had no idea on how to use them for multiple outputs, so used Logic Friday to solve the truth table for me.
These were the formula I got from Logic Friday for each of the four outputs :
Z1 = A B;
Z2= A B';
Z3 = A' B + A B';
Z4 = A' B + A B;
By minimizing them I got:
Z1 = A B;
Z2= A B';
Z3 = A B' + A' B;
Z4 = B;
I assembled the circuit using these four formula output and it worked perfectly.
I though I could not find any info on how to solve these because they were going to be taught on the next chapter, maybe using K mapping, but now I still don't have any idea on how we got from this:
To this:
Z1 = A B;
Z2= A B';
Z3 = A' B + A B';
Z4 = A' B + A B;
Can someone please tell me how are those formula obtained from and the procedure involved?
Thanks!
