Because T1=1 covers 3 rows and the values of A3 and A4 don't matter, then T0S covers the remaining row and again A3 and A4 don't matter.Yeah I get that, but for the first table for DG0, shouldn't it be T0S + T1 + T1A3 + T1A3A4. Why is it only T0S + T1
Ask yourself what the minimum amount of information you need to know is in order to determine the value of a particular variable.I still dont't understand the second table. So to get T0, I have to check which row is set to 1 in T0, which are rows 1 and 2. The S input is either 0 or 1 so it becomes a don't care, the G1 are both 0 so it doesn't go to the equation and G0 is either 0 or 1. Then there is no equation for T0? How did they get G'0? Im confused.
Since the assignment specifically stated that state {10} is a "don't care" state, this would be strictly legal. Most people that have worked in the real world don't believe that there is such a thing as a "don't care" state -- at least not until it has been investigated an proven that it truly is a "don't care". But that almost always requires knowledge of the system beyond that which you have access to in a homework assignment.In the case of T1 can I use XOR? so it will be G1 XOR G0
