I'm stuck on an engineering question about boolean algebra. I've been trying all day and asked my other students however I am still stuck. Could you please help me to draw a logic diagram and truth table for the Boolean expression "(A + B) . (A + C)". I also need to minimize the expression and do a logic circuit and truth table for it also.
I tried first attempt and got this:
However I am not sure if it was right so I started researching and got this for my second attempt:
I haven't completed the truth table, it's wrong I think. Could you guys comment on which attempt was the correct one, thank you!
My final attempt:
Please tell me someone, is this finally correct? Both truth tables and logic diagrams?
