## How do I get a NOR gate from NAND?

To make a NOR gate perform the NAND function, we must invert all inputs to the NOR gate as well as the NOR gate’s output. For a two-input gate, this requires three more NOR gates connected as inverters.

**How many NAND gates are used to form a NOR gate?**

Thus total three NAND gates will be required. Four.

### Is a NOR gate same as NAND?

A NOR gate is equivalent to an inverted-input AND gate. An OR gate is equivalent to an inverted-input NAND gate. Two NOT gates in series are same as a buffer because they cancel each other as A” = A.

**How logical effort is always 2 for multiplexer?**

The total logical effort of a multiplexer is n 4 + 4 = 1 + = 4n. The logical effort per data input is just 2 + 2 = 1 + =2, and the logical effort per select bundle is also 2. Note that the logical effort per input of a multiplexer does not depend on the number of inputs.

## HOW IS AND gate obtained by NOR gate?

An AND gate gives a 1 output when both inputs are 1. Therefore, an AND gate is made by inverting the inputs of a NOR gate. Again, note that a NOT gate is equivalent to a NOR with its inputs joined.

**How can we implement AND gate using NOR gate?**

An AND gate gives a 1 output when both inputs are 1. Therefore, an AND gate is made by inverting the inputs of a NOR gate. Again, note that a NOT gate is equivalent to a NOR with its inputs joined….AND.

Input A | Input B | Output Q |
---|---|---|

0 | 1 | 0 |

1 | 0 | 0 |

1 | 1 | 1 |

### How does a NOR gate work?

The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator.

**What does a NOR gate do?**

The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results.

## What is parasitic delay?

Parasitic delay of the gate, is the delay when the gate drives zero load. It is comfortable to use the term of normalised parasitic delay, which is the ratio of diffusion capacitance to the gate capacitance of certain process.

**How can I get AND gate using NAND gate?**

AND: You can create an AND gate by using two NAND gates. The first NAND gate does what NAND gates do: returns LOW if both inputs are HIGH and returns HIGH if both inputs are anything else. Then the second NAND gate is configured as a NOT gate to invert the output from the first NAND gate.
