## What will be the output of a 2 inputs NAND gate?

By De Morgan’s laws, a two-input NAND gate’s logic may be expressed as AB=A+B, making a NAND gate equivalent to inverters followed by an OR gate. The NAND gate is significant because any boolean function can be implemented by using a combination of NAND gates. This property is called functional completeness.

## 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”.

**How many possible gates are there with two inputs and one output?**

For example, the gate A and B is a logic gate with 2 inputs and 1 output. There are exactly 16 of them, because: each logic gate takes two inputs, which can be truthy or falsey, giving us 4 possible inputs.

**What is the minimum number of NAND gates required to implement a 2-input exclusive OR function without using any other logic gate?**

4 NAND gates

What is the minimum number of NAND gates required to implement a 2-input EXCLUSIVE-OR function without using any other logic gate? Question 6 Explanation: To create 2-input Exclusive-OR function we require 4 NAND gates.

### When an input of NAND gate is combined the gate form is?

NOT Gate: You may simply connect the two inputs in the NAND gate together to create a NOT Gate from the NAND Gate. Since the two inputs of the NAND gate are connected, only two input combinations can be used. The NAND Gate will emit a LOW if any input is HIGH. The NAND gate would be output HIGH if all inputs are LOW.

**Which gate will a NAND gate be equivalent to when two inputs of NAND gates are shorted?**

When two inputs of a NAND gate are shorted, the resulting circuit acts as a NOT gate. Hence in the given figure the input A and B are connected to a NOT gate and the resulting output of both the NOT gate is given to a NAND gate. Hence, the resultant gate is OR gate.

**When an input of NAND gate is combined the gate formed is?**

NOT: You can create a NOT gate from a NAND gate simply by tying the two inputs of the NAND gate together. Because the two inputs of the NAND gate are tied together, only two input combinations are possible: both HIGH or both LOW. If both inputs are HIGH, the NAND gate will output a LOW.

#### How many two input AND gates and two input OR gates are required to realize?

9. How many two input AND gates and two input OR gates are required to realize Y = BD + CE + AB? Explanation: There are three product terms. So, three AND gates of two inputs are required.

#### How many 2-input NAND gates are required to implement a 2-input AND gate?

The number of 2-input NAND gates required to implement a 2-input XOR gate is 4. Similarly, the number of 2-input NOR gates required to implement a 2-input XNOR gate is 4.

**How many 2-input NAND gates are required to make a NOR gate?**

NOR: It takes four NAND gates to create a NOR gate. This circuit is the same as the OR gate circuit, with the addition of another NOT gate to invert the output from the third NAND gate.

**How many NAND gates are used to form an AND gate?**

two NAND gates

If none of the AND gate’s inputs are HIGH, the output is LOW. Using two NAND gates one can make an AND gate.

## Is the output of the NAND gate always true?

NAND Gate Truth Table The output of the NAND gate is always at logic high/”1″ and only goes to logic low/”0″ when all the inputs to the NAND gate are at logic 1. In other words, we can say that the output of the NAND gate always continues true if at least one of its inputs remains false or logic low.

## Can a half adder circuit be implemented using NAND gates?

As we know that NAND and NOR are called universal gates as any logic system can be implemented using these two, the half adder circuit can also be implemented using them. We know that a half adder circuit has one Ex – OR gate and one AND gate.

**Which is the symbolic representation of the NAND gate?**

The NAND gate is represented by a symbol whose shape matches the AND gate with a circle followed, often identified as an inversion circle. Below is the symbolic representation of the NAND gate. The output of the NAND gate is always at logic high/”1″ and only goes to logic low/”0″ when all the inputs to the NAND gate are at logic 1.

**Is there a truth table for the NAND gate?**

The logic or Boolean expression or the NAND gate is the logical multiplication of the inputs followed by the complement of the obtained output or the logical addition of the complemented inputs. Below is the truth table for the two-input NAND gate. Learn about various types of Computer Storage Devices here.
