What is the output of a NAND gate when both its inputs are 1?
The NAND (Not – AND) 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”.
Which Gates give output as one if all inputs signals are 1?
XOR gate – output is 1 if ONLY one input is 1.
Which gate will give an output of 1 when both its input is 1 or both inputs is 0 but gives an output of 0 when any of its input is different from the other?
XOR gate
An XOR gate is normally two inputs logic gate where the output is only logical 1 when only one input is logical 1. When both inputs are equal, either are 1 or both are 0, the output will be logical 0. This is the reason an XOR gate is also called an anti-coincidence gate or inequality detector.
How do you make an OR gate with NAND gates?
OR: You need three NAND gates to create an OR gate. First, you use a pair of NAND gates configured as NOT gates to invert the two inputs. Then the third NAND gate produces a LOW output if both of the original inputs are LOW.
Which gate has only one input?
NOT gate
A logical inverter, sometimes called a NOT gate to differentiate it from other types of electronic inverter devices, has only one input. It reverses the logic state. If the input is 1, then the output is 0. If the input is 0, then the output is 1.
Why NAND gate is called universal gate?
An OR gate can be replaced by NAND gates as shown in the figure (The OR gate is replaced by a NAND gate with all its inputs complemented by NAND gate inverters). Thus, the NAND gate is a universal gate since it can implement the AND, OR and NOT functions.
How to convert not-and-or circuit to NAND equivalent?
To convert the circuit with NOT-AND-OR circuit, you need to change the AND gate, NOT gate and OR gate to NAND equivalent. You will change AND gate with NAND gate first and then change the OR gate with NAND gate. The NAND gate equivalent of inverter is created using a single NAND gate with two input X which gets inverted at the output to give X’.
How many NAND gates are used in a full adder circuit?
The circuit of full adder using only NAND gates is shown below. Full adder is a simple 1–bit adder. If we want to perform n–bit addition, then we need ‘n’ number of 1–bit full adders should be used in the form of a cascade connection. A complete tutorial on Half Adder and Full Adder Circuits.
How to draw logic diagram using NAND as universal gate?
In this post you learn to use NAND as universal gate to create a logic diagram of a digital circuit with simple gates. If you want to learn more about logic gates visit following links. F = X + Y’Z is the given function. Show the result in truth table and draw a logic diagram using only NAND gate.
What is the use of NAND gate in Computer Science?
In computer science, logic gates such as NAND gates are very useful. You can use NAND gate as universal gate. They can be helpful in designing any complex logic circuit its implementation using NAND gates only. In this post you learn to use NAND as universal gate to create a logic diagram of a digital circuit with simple gates.
