The logic symbol, its corresponding function, and the truth table defining the operation are shown. The NOT function inverts the signal (i.e., a 1 becomes a 0 and a 0 becomes a 1). The AND function generates a true, or 1, if both inputs are 1; otherwise the output is false, or 0. The OR function generates a 1, or true, if either input is a 1, or true, value.
