Find out an expression for X in the truth table from the circuit below?

Posted 8 years ago

I have only just stared looking at Boolean Algebra and I am a bit stuck. Can anyone explain what Boolean expression represents the circuit and why. And also find out an expression for X from the truth table and explain why. Thanks enter image description here

Next time post what you have TRIED!

tf={True,False};
out=Table[{a,b,c,And[Or[Not[c],b],a]},{a,tf},{b,tf},{c,tf}];
out=Join@@out;
out=Join@@out;
TableForm[out,TableHeadings->{None,{"a","b","c","out"}}]

Second problem can be solved like this:

BooleanConvert[
 BooleanFunction[{{True, True, True} -> False, {True, True, False} -> 
     True, {True, False, True} -> False, {True, False, False} -> 
     False, {False, True, True} -> True, {False, True, False} -> 
     False, {False, False, True} -> True, {False, False, False} -> 
     False}][a, b, c]]
