## Which logic gate is a parity checker?

XOR gates

A parity checker is designed by using XOR gates on the bits of the data. An XOR gate will output a “0” if bits are similar, or a “1” if the bits differ.

## What is parity bit generator?

The parity generator and parity checker’s main function is to detect errors in data transmission and this concept is introduced in 1922. The parity bit is an extra bit that is set at the transmission side to either ‘0’ or ‘1’, it is used to detect only single bit error and it is the easiest method for detecting errors.

**What is Hamming code with example?**

Hamming code is a set of error-correction code s that can be used to detect and correct bit errors that can occur when computer data is moved or stored. Hamming code is named for R. W. Hamming of Bell Labs. To enable this, a transmitting station must add extra data (called error correction bits ) to the transmission.

### What is parity check explain with example?

As an example, if the original data is 1010001, there are three 1s. If the original data contains an even number of 1s (1101001), then parity bit of value 1 is added to the data’s left side to make the number of 1s odd, if odd parity checking is used and data transmitted becomes 11101001.

### Are there any real solutions to the quadratic equation?

Many physical and mathematical problems are in the form of quadratic equations. In mathematics, the solution of the quadratic equation is of particular importance. As already discussed, a quadratic equation has no real solutions if D < 0. This case, as you will see in later classes is of prime importance.

**When do you use a quadratic equation for revenue?**

Because the quantity of a product sold often depends on the price, you sometimes use a quadratic equation to represent revenue as a product of the price and the quantity sold. Quadratic equations are also used when gravity is involved, such as the path of a ball or the shape of cables in a suspension bridge.

#### Is there a quadratic formula for the area problem?

The area problem below does not look like it includes a Quadratic Formula of any type, and the problem seems to be something you have solved many times before by simply multiplying. But in order to solve it, you will need to use a quadratic equation. Bob made a quilt that is 4 ft × × 5 ft.

#### How is the quadratic equation used in free fall?

In the next video we show another example of how the quadratic equation can be used to find the time it takes for an object in free fall to hit the ground. Here are some more similar objects in free fall examples. A ball is thrown upward from the top of a 40 foot high building at a speed of 80 feet per second.
