The symbol and truth table of an AND gate with two inputs is shown below. The NOT gate (also known as inverter gate) is a digital electronic logic gate. Logic gates have a lot of applications but they are mainly based upon their mode of operations or their truth table. Just as the NAND gate could be thought of as an AND followed by a NOT, a NOR can be thought of as an OR also followed by a NOT. Select the number of variables, then choose SOP (Sum of Products) or POS (Product of Sums) or Quine-McCluskey, and try some calculations. LogicalSolver supports you in solving a logic grid puzzle that is also known as logical, logigram or logiquiz . Table 4-1 Basic rules of Boolean algebra. If neither input is 1, the output will be 0. If one or both the inputs to the gate are HIGH (1) it produces HIGH (1) output as results. A logic gate is a piece of an electronic circuit, that can be used to implement Boolean expressions.Laws and theorems of Boolean logic are used to manipulate the Boolean expressions and logic gates are used to implement these Boolean expressions in digital electronics. The NOT gate is also known as an inverter because the output is the exact opposite of the input. 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. The name NAND comes from joining NOT and AND. Select gates from the dropdown list and click "add node" to add more gates. How the logic circuits can be designed using these gates? Logic gates operate on binary logic 0 and 1 where 0 indicates low and 1 indicates a high voltage level. The symbol for NAND is the same as that for AND except for the addition of a small circle on the right side. 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.
