Any ideas if I should just leave it in this situation or connect?

I've got the main stuff worked out but a little line in the coursework is making me think if I need to add a couple of extra connections on it. The circuit has 7 incrementing values and 2 outputs. Basically, my first output is going to be 0,0 and so I originally thought that I wouldn't need any connections to the AND gate or to the OR gates, however I noticed my notes saying that the AND gate would float high and give a false 1 o/p from it. Now if it was connected straight to a single OR gate this would give a false o/p but I have to connect the AND and OR gate lines myself (as there are 2 o/p's) . My question is this - if I leave the lines unconnected would the OR gate input float high too? My notes say that the 'product line' (AND gate I/p line) would go high but says nothing about the 'product term' (OR gate I/p line). My notes say that to get round this we just connect both outputs of the buffer that go to the AND gate.
Any ideas if I should just leave it in this situation or connect?
PLA circuit confusion refers to a situation where there is difficulty in understanding or interpreting the operation of a programmable logic array (PLA) circuit. PLAs are a type of digital logic device used in electronic circuits, and confusion can arise due to complex designs or errors in the circuit.
PLA circuit confusion can be caused by a variety of factors, such as errors in the circuit design, faulty components, or incorrect programming. It can also be a result of not fully understanding the operation of the PLA and how it interacts with other components in the circuit.
To troubleshoot PLA circuit confusion, it is important to first carefully review the circuit design and programming to check for any errors. Testing individual components and connections can also help identify any faulty components. Additionally, consulting with other experts or referencing technical resources can provide valuable insight and guidance.
Yes, there are several common solutions for resolving PLA circuit confusion. These include double-checking the circuit design and programming for errors, replacing any faulty components, and seeking guidance from other experts or technical resources. In some cases, simplifying the circuit design or breaking it down into smaller sections can also help identify and resolve the confusion.
To prevent PLA circuit confusion in the future, it is important to carefully plan and design the circuit, thoroughly test and troubleshoot before implementation, and seek guidance from experts when needed. Keeping thorough documentation and records of the circuit design and any changes made can also help prevent confusion and aid in troubleshooting in the future.
