The logic gate in the given diagram is an AND gate. An AND gate is a digital logic gate that has two or more inputs and produces an output that is the logical conjunction of the inputs. In an AND gate, the output is only HIGH when both the inputs are HIGH. In the given diagram, the two inputs are A and B, and the output is Y. Therefore, if A and B are both HIGH, then the output Y will be HIGH, otherwise, it will be LOW.
