Hello, my lecturer gave us this logic diagram and truth table, but I am confused by the outcome of the first truth table line eg. A0, B0, C0.
Should that line not equal 1 ?

Also, is the Boolean expression correct for this diagram ?

Thanks kindly for any help.

 

Quite correctly, first line's result is 1.

But the parenthesis in the boolean expression defies every mathematical convetion: Enclosing only a term and an operator? Just kidding, I 'm sure it's just a typo.

The correct form is \(f=\bar{AB+(B+C)}\).
