This might be tedious to describe but this is what I've worked out.My guess is that it's look like the
top one is an AND gate with a not gate on the third (letter ¬¬C) "prong" into it and a not gate on it's
end (ABC).Below that is a "one prong" OR gate (D).Below that one is a "two prong" AND gate with
a not gate on the lower prong.Below that one is an OR gate that is two pronged with a not gate on
the lower one with a "D".Below that is an AND gate with not gates going into both the (¬B and ¬D)
prongs.Is this right?.
My personal way of describing them AND gate=semi circle
