Hello everyone, this is the first time programming a digital board without hardwiring. I'm confused on what the truth table of a "negative-logic OR" would look like:(adsbygoogle = window.adsbygoogle || []).push({});

The diagram looks like

Two inputs and 1 output, its an OR gate but both the inputs are sent through an inverter and the output is also inverted so i got the following boolean expression:

_____

'A + 'B = AB

so using Demorgans theroem i get AB,

so if this is the case, the truth table would be

A B Output

0 0 0

0 1 0

1 0 0

1 1 1

is that right?
