Answer:

Step-by-step explanation:

To design a state diagram, table, K-map, and equation for a parking lot with an up-down counter application, we need to follow these steps:

Define the problem and identify the inputs and outputs.

Create a state diagram to represent the behavior of the system.

Generate a state table based on the state diagram.

Simplify the state table using Karnaugh maps (K-maps).

Derive a minimized equation for the next state.

Implement the equation using D flip-flops.

Step 1: Define the problem and identify the inputs and outputs.

The problem is to design a parking lot with an up-down counter application. The input to the system is a signal that indicates whether a car has entered or exited the parking lot. The output is the current number of cars in the parking lot.

Step 2: Create a state diagram to represent the behavior of the system.

The state diagram for the parking lot with an up-down counter application is as follows:

+-----+ +-----+

| | | |

| | | |

V | | V

+------------+ | +------------+

| Car Enters | | | Car Exits |

+------------+ | +------------+

| | | |

| V V |

| Count Up/Down |

| |

+-----------------+

Step 3: Generate a state table based on the state diagram.

Copy code

+------------+------------+------------+------------+

| Current | Input | Next State | Output |

| State | | | |

+------------+------------+------------+------------+

| 00 | 0 | 00 | 00 |

| 00 | 1 | 01 | 01 |

| 01 | 0 | 01 | 01 |

| 01 | 1 | 10 | 02 |

| 10 | 0 | 10 | 02 |

| 10 | 1 | 11 | 03 |

| 11 | 0 | 11 | 03 |

| 11 | 1 | 10 | 02 |

+------------+------------+------------+------------+

Step 4: Simplify the state table using K-maps.

We can simplify the state table using K-maps as follows:

| 00 | 01 | | 01 | 10 |

| | | | | |

+-------+-------+ +-------+-------+

Input: 0 Input: 1

+-------+-------+ +-------+-------+

| | | | | |

| 01 | 10 | | 11 | 10 |

| | | | | |

+-------+-------+ +-------+-------+

Input: 0 Input: 1

Step-by-step explanation:

To design a state diagram with table, Karnaugh map, and equation for a parking lot with an up-down counter application, we can follow these steps:

Step 1: Define the states

In this system, we need to keep track of the number of available parking spots. We can represent the states as the binary values of the up-down counter. For example, if we have a 4-bit up-down counter, the possible states are: 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, and 1111.

Step 2: Define the inputs and outputs

In this system, the input is the signal to increment or decrement the counter. The output is the number of available parking spots.

Step 3: Draw the state diagram

The state diagram for a 4-bit up-down counter is shown below:

+-------+ 0/0 +-------+

| | <------------- | |

+--------> 0000| | 1111 <--------+

| | | | | |

| +-------+ +-------+ |

| | ^ ^ | |

| 1/0 | | 0/1 1/0 | | 0/1 | 1/0

| v | | v |

| +-------+ +-------+ |

| | | | | |

+--------> 0001| | 1110 <--------+

| | | | | |

| +-------+ +-------+ |

| | ^ ^ | |

| 1/0 | | 0/1 1/0 | | 0/1 | 1/0

| v | | v |

| +-------+ +-------+ |

| | | | | |

+--------> 0010| | 1101 <--------+

| | | | | |

| +-------+ +-------+ |

| | ^ ^ | |

| 1/0 | | 0/1 1/0 | | 0/1 | 1/0

| v | | v |

| +-------+ +-------+ |

| | | | | |

+--------> 0011| | 1100 <--------+

| | | | | |

| +-------+ +-------+ |

| | ^ ^ | |

| 1/0 | | 0/1 1/0 | | 0/1 | 1/0

| v | | v |

| +-------+ +-------+ |

| | | | | |

+--------> 0100| | 1011 <--------+
