AND

This is one of the standard logical operators. For two logic inputs A, B the output is true - (logic 1) only if both inputs are true otherwise it is false (logic 0)

In Boolean algerbra notation the AND operation is usually indicated by a dot between the inputs

Q = A.B

Multi-input AND gates are also available, in which case every input has to be true for the output to be true.
