Digital Design Realising Function

AI Thread Summary
The discussion focuses on determining the number of gates created for Q+ using original and inverted variables, with participants seeking methods rather than direct answers. A Karnaugh map is suggested as a tool for minimizing combinatorial logic, and the possibility of using gates with more than two inputs is raised. Participants express confusion about arriving at the answer of 10 gates, questioning the role of outputs like 'u' in the total count. The conversation emphasizes the importance of drawing state diagrams to clarify the problem. Overall, the thread highlights the complexities of digital design in realizing function through logical gate implementation.

how many gates are created for Q+ using all original and inverted variables?
dont want the answer, but a way of solving it? i know it has 3 flipflops and 8states.

You would probably use a Karnaugh map to minimize the combinatorial logic. Can you use gates with more than 2 inputs? Have you drawn the State Diagrams associated with this problem?

the Answer is 10 but i have no idea how they got 10 from. do you think you know? thanks

How about showing us the work that I suggested in Post #2? :smile:

Is u an output and not counted in the Q+ logic gate total? And if both x and x' are given, isn't 10 the obvious answer if the equations are implemented exactly as written?
