Learn How to Use Logic Gate Calculator
Posted by Dinesh onEasily Evaluate Logic Gate Expressions
Calculate logic gate output for OR, AND, NOT, NAND, NOR, XOR, XNOR gates in digital circuitry by using online logic gate calculator with truth table.
AND Gate
The AND gate is a basic a digital electronic logic gate which gives an output HIGH (1) as a result, if both the inputs are High (1), and if neither or only one input is HIGH to the AND gate then output will be LOW (0).

OR Gate
The OR gate is a digital electronic logic gate. If one or both the inputs to the gate are HIGH (1) it produces HIGH (1) output as results. If neither input is high, the output results will be LOW (0).

NOT Gate
The NOT gate (also known as inverter gate) is a digital electronic logic gate. If input is HIGH (1), it produces LOW (0) as output result and if input is LOW (0), it produces HIGH (1) as output result.

NAND Gate
The NAND gate (also known as negative - AND) is a digital logic gate which produces an output result as HIGH (1), if one or both inputs are LOW (0). If both the inputs to the NAND gate are HIGH (1) the output results will be LOW (0).

NOR Gate
The NOR gate (also known as negative - OR) is a digital logic gate which produces an output result as HIGH (1), if both the inputs to the gate are LOW (0) and if one or both inputs is HIGH (1) then the output result as LOW (0).

XOR Gate
The XOR gate (sometimes called as Exclusive OR) is an electronic logic gate, and the output is true if any of only on input true to the gate. If both of the inputs are HIGH (1) or LOW (0) then the output is the LOW (0). i.e., the output is HIGH (1) if the inputs are not alike otherwise the output is LOW (0).

XNOR Gate
The XNOR gate (sometimes called as Exclusive-NOR) is an electronic logic gate and it works as the logical complement of the exclusive OR (XOR) gate. If both of the digital inputs to the gate are the same, then output will be HIGH (1). If one but not both inputs are HIGH (1), then output will be LOW (0).
