Array of logic gates that provides for the binary addition of two binary numbers. Figure 3: A simple logic circuit. 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.

Array of logic gates that provides for the binary addition of two binary numbers.

In electronics, a logic gate is a fundamental component of digital circuits. These gates are built using integrated circuits and operate on a two-valued logic system (1/0, on/off) based on Boolean algebra.

Logic gates receive input signals, process them, and produce an output signal. They act like switches, passing or blocking electrical pulses. The three basic types are:
* AND: Outputs 1 only if all inputs are 1.
* OR: Outputs 1 if at least one input is 1.
* NOT: Inverts the input; outputs 1 if the input is 0, and 0 if the input is 1.

Other gates like NAND, NOR, XOR, and XNOR are combinations of these basic types. By connecting logic gates, complex devices capable of performing arithmetic functions can be constructed.1
