“X-OR gate is a combinational logic gate of all basic gates”-Explain. “NAND gate is called universal gate”-Explain. “NOR gate is called universal gate”-Explain. The following Boolean Expression can be written from the above truth table of XNOR gate using SOP method-įig: Implementation of XNOR gate using Basic gates The X-NOR gate is also called the composite gate and the special gate. The X-NOR gate has two or more input lines and only one output line. আরো পড়ুন :: Second Chapter Lesson-4: Wired Medium (Twisted Pair Cable, Co-axial & Fiber Optic Cable). An even number of logic “1’s” on its inputs gives a logic “1” at the output, otherwise is at logic level “0”. The logic symbol for an Exclusive-NOR gate is simply an Exclusive-OR gate with a circle or “inversion bubble”, ( ο ) at its output to represent the NOT function. That is, by reversing the output of the X-OR gate, the output of the X-NOR gate is obtained. If the output of the X-OR gate is propagated to the NOT gate, then the X-NOR gate is available. This is a compound gate made up of AND, OR and NOT gates.

It is combination of the Exclusive-OR gate and the NOT gate connected together in series that is also the reverse or complementary of the Exclusive-OR gate. The Exclusive NOR Gate is abbreviated as the X-NOR Gate. The following Boolean Expression can be written from the above truth table of XOR gate using SOP method. Implementation of the above Boolean Expression-įig: Implementation of XOR gate using Basic gates 3-input Ex-OR Gate The following Boolean Expression can be written from the above truth table of XOR gate using SOP method. The X-OR gate is also known as the compound gate and the special gate. The Exclusive-OR logic gate is very useful circuit that can be used in many different types of computational circuits. It is used extensively in building arithmetic logic circuits, computational logic comparators and error detection circuits. The X-OR gate has two or more input lines and only one output line. The X-OR operation is represented by ⊕ simbol. The output is “1” when there are an odd number of 1’s in the inputs. The output signal is obtained by comparing different input bits through this gate. The Exclusive OR Gate is abbreviated as the X-OR Gate. These two “hybrid” logic gates are called the Exclusive-OR (Ex-OR) Gate and its complement the Exclusive-NOR (Ex-NOR) Gate. NAND gate is also known as compound gate and universal gate.ģ-input Logic NAND Gate: Exclusive Gates: The NAND gate has two or more input lines and only one output line. আরো পড়ুন :: Sixth Chapter Lesson-9: Corporate database and database in government organizations The Logic NAND Gate is the reverse or “Complementary” form of the AND gate we have seen previously. The NAND gate has an output that is normally at logic level “1” and only goes “LOW” to logic level “0” when ALL of its inputs are at logic level “1”.

That is, by reversing the output of the AND gate, the output of the NAND gate is obtained. If the output of the AND gate is propagated to the NOT gate, then the NAND gate is available. The Logic NAND Gate is a composite gate which is combination of a logic AND gate and a NOT gate connected together in series. NOR gate is also known as compound gate and universal gate. The NOR gate has two or more input lines and only one output line. The Logic NOR Gate is the reverse or “Complementary” form of the inclusive OR gate we have seen previously. The inclusive NOR gate has an output that is normally at logic level “1” and only goes “LOW” to logic level “0” when ANY of its inputs are at logic level “1”. That is, by reversing the output of the OR gate, the output of the NOR gate is obtained.

If the output of the OR gate is propagated to the NOT gate, then the NOR gate is available. The Logic NOR Gate is a compound gate which is combination of the logic OR gate and an NOT gate connected together in series. This is because only NAND gate or only NOR gate can implement all the basic gates (AND, OR, NOT) as well as any gate and any circuit.These gates are widely used in digital circuits as these cost less to make. NAND and NOR gates are called universal gates. The gate which can implement all the basic gates (AND, OR, NOT) as well as any gate and any circuit is called a universal gate. Go for Bangla Version Compound/Composite Gates:Ī gate that is created using two or more basic gates is called a composite or compound gate. For example-ĪND Gate +NOT Gate = NAND Gate, OR Gate + NOT Gate = NOR Gate.
