Linking unconnected circles and including the redundant term can prevent some kinds of basic hazard ( more than one input changing at a time, not in perfect sync, the output can go through an intermediate state ). If you were paying attention at just the wrong time, you may have gotten the idea that linking the circles was required.
Oh my goodness. How do you get AB'+BC' from AB'+AC'+BC'. Please. I was given an assignment and from a logic circuit I was about to write an initial expression and from there I simplified it down to AB'+BC'. I created a truth table with the simplified expression. Using the truth table I made a Karnaugh Map and from the K-Map I got AB'+AC'+BC'. Ugh! Using Multsim I checked everything and it's all right! The truth tables are the same for both expressions. I can't figure out for the life of me how the K-Map expression is reduced to what I got initially.Please help.
