Explain how an EVEN PARITY Circuit would be created and show the EVEN PARITY TRUTH table. Please do this in multisim

Answers

Answer:

Explanation:

Creating an even parity circuit in Multisim involves designing a digital logic circuit that checks if the number of '1's in a binary input is even. If the input has an even number of '1's, the circuit should output '1' (indicating even parity); otherwise, it should output '0' (indicating odd parity).

Here's how to create an even parity circuit in Multisim, along with the truth table:

**Creating the Even Parity Circuit:**

1. Open Multisim and create a new blank schematic.

2. Add the following components to your schematic:

  - Input pins (for binary input bits)

  - XOR gates

  - An AND gate

  - An inverter (NOT gate)

  - Output display (LED or probe)

3. Connect the input pins to the XOR gates. Each input pin corresponds to one bit of the binary input.

4. Connect the outputs of the XOR gates to the inputs of the AND gate.

5. Connect the output of the AND gate to the input of the inverter (NOT gate).

6. Connect the output of the inverter to the output display.

7. Label your input pins for clarity (e.g., A0, A1, A2, ...).

**Designing the Even Parity Truth Table:**

To create the truth table for even parity, you'll need to list all possible input combinations (binary numbers) along with the corresponding output (even or odd).

Assuming you have a 3-bit input (A2, A1, A0), here's the truth table:

| A2 | A1 | A0 | Output (Even Parity) |

|----|----|----|-----------------------|

| 0  | 0  | 0  | 1 (Even)              |

| 0  | 0  | 1  | 0 (Odd)               |

| 0  | 1  | 0  | 0 (Odd)               |

| 0  | 1  | 1  | 1 (Even)              |

| 1  | 0  | 0  | 0 (Odd)               |

| 1  | 0  | 1  | 1 (Even)              |

| 1  | 1  | 0  | 1 (Even)              |

| 1  | 1  | 1  | 0 (Odd)               |

Each row in the truth table represents a unique combination of input bits (A2, A1, A0) and specifies whether the output is '1' (Even) or '0' (Odd).

Once you have created the circuit in Multisim and designed the truth table, you can simulate the circuit to verify its functionality. Ensure that the circuit produces the expected output (even parity) based on the input values.

The idea that Jacob uses photocells for all the energy need in the park is a good idea. In this way, he is saving so much electricity because photocells are renewable source of energy. The energy can be used for a lifetime, however, its main disadvantage is that no electricity will be produced if sunlight is not present.

You're conducting a physics experiment on another planet. You drop a rock from a height of 1 m and it hits the ground 0.4 seconds later. What is the acceleration due to gravity on this planet?

Answers

First, we must assume that the planet has no atmosphere, so there's no air resistance,
and the behavior of the rock is the result of gravity and nothing else.

The formula for the distance covered by anything that accelerates from rest is

D = (1/2) (acceleration) (time)²

In this problem, we're given the distance and the time, and we want to find the acceleration.

1 = (1/2 acceleration) x (0.4)²

0.4² = 0.16

1 = (1/2 times 0.16) (acceleration)

1 = 0.08 acceleration

Acceleration = 1/0.08 = 12.5 meters per second²

That's about 27% greater than Earth's gravity.

Answer:

12.5
