My intro to digital system teacher is hard. He gives question that ask u design circuit such as make a counter that count 3 5 9 0 3 using mod-6 counter + encoder + decoder. Do question like this have a systematic way of solving or is only solvable if u have mad experience? He seems to give question that test ur EXPERIENCE rather than steps. What should I do? I don't think I can do every problem cuz heisquestions have a big range.
