Problem: Explain why this circuit does not work for Fan-In=1 and Fan-Out=3 for all logic gates(including the complex logic gate).
Firstly, I would say the Inverter Gate is fine because it does not violate the Fan-Out=3. But I don't know what the problem is in the case of Fan-In=1.
Secondly, I would say that because x is routed to the 3 inputs of the complex logic that the Fan-In=3 thus it would overload the inverter thus making the gate not work properly.
Am I right? Hope somebody can give me a lead and or help me.
