(Counter Design) Consider the design of a 4-bit Gray-code counter (that is, only one of the state bits changes for each transition) that counts in the following sequence: 00,0001,0011,0010,0110,01110101,0100,1100,1101,1111 11101010, 1011, 1001, 1000,and then back to 0000,00011 etc(a)Draw a state diagram and next-state table.

Here is the state diagram and next-state table for the 4-bit Gray-code counter:


| Current State | Next State |
| --- | --- |
| 0000 | 0001 |
| 0001 | 0011 |
| 0011 | 0010 |
| 0010 | 0110 |
| 0110 | 0111 |
| 0111 | 0100 |
| 0100 | 1100 |
| 1100 | 1101 |
| 1101 | 1111 |
| 1111 | 1110 |
| 1110 | 1010 |
| 1010 | 1011 |
| 1011 | 1001 |
| 1001 | 1000 |
| 1000 | 0000 |

Figure shows a 3-bit gray code representing the decimal numbers from 0 to 7. Design a modulo-8 Gray code counter with three outputs (y2,y1,y0) to represent the decimal count.When reset input is asserted the output should be 000 please complete the State transition/Output Table and then draw the State Transition Graph

Sure, here is the completed State transition/Output Table:

| Present State | Next State | Output |
|---------------|------------|--------|
| 000 | 001 | 001 |
| 001 | 011 | 010 |
| 011 | 010 | 011 |
| 010 | 110 | 100 |
| 110 | 111 | 101 |
| 111 | 101 | 110 |
| 101 | 100 | 111 |
| 100 | 000 | 000 |

And here is the State Transition Graph:

           +--(001)-+
           |        |
    +->(000)       (011)<--+
    |      |        |      |
    |      |        |      |
  (100)-->(101)--(111)-->(110)
    |      |        |      |
    |      |        |      |
    +--(111)-+        +--(010)-+
           |                   |
           +--(110)------------+

I hope this helps!

Write an essay of 400-500 words to compare/contrast one of the following pairs with either alternative or block pattern:

When it comes to writing an essay, one of the most important things to consider is the structure. Choosing the right pattern can make a significant impact on the quality of your essay. In this essay, we will compare and contrast the alternative and block pattern and analyze their advantages and disadvantages.

The alternative pattern, also known as the point-by-point pattern, is a method of organizing an essay where you alternate between discussing one point of comparison and then the other. This pattern is best for essays that compare and contrast two topics that have many similarities and differences. For instance, if you are comparing two different types of dogs, you could discuss their similarities and differences on a point-by-point basis.

On the other hand, the block pattern, also known as the subject-by-subject pattern, is a method of organizing an essay where you discuss all the points for one subject first, then move on to the next subject. This pattern is best for essays that compare and contrast two topics that have significant differences. For example, if you are comparing and contrasting two different types of music, you could discuss all the aspects of one type of music, then move on to the other type.

There are advantages and disadvantages to both patterns. The alternative pattern is great for essays that have a lot of similarities and differences, as it allows you to discuss each point in depth. However, it can be challenging to keep track of all the different points, and the essay may end up feeling disconnected.

The block pattern is excellent for essays that have a lot of differences, as it allows you to focus on each subject completely. However, it can be challenging to compare and contrast the subjects in a detailed manner. Additionally, it can be challenging to transition from one subject to another.

In conclusion, choosing the right pattern for your essay is crucial in ensuring that it is well-structured and easy to read. Both the alternative and block patterns have their advantages and disadvantages, and the choice largely depends on the nature of the essay. If you are comparing and contrasting two topics that have many similarities and differences, the alternative pattern is the way to go. On the other hand, if you are comparing and contrasting two topics that have significant differences, the block pattern is the way to go. Ultimately, the key is to choose the pattern that will best help you convey your ideas and arguments effectively.
