A sequence detector is designed to detect precisely 3 digital inputs, with overlapping sequences detectable. For the sequence (1,0,1) and input data (1,1,0,1,0,0,1,1,0,1,0,1,1,0), what is the output of this detector?
  • a)
    1,1,0,0,0,0,1,1,0,1,0,0
  • b)
    0,1,0,0,0,0,0,1,0,1,0,0
  • c)
    0,1,0,0,0,0,0,1,0,1,1,0
  • d)
    0,1,0,0,0,0,0,0,1,0,0,0
Correct answer is option 'B'. Can you explain this answer?

A sequence detector is designed to detect precisely 3 digital inputs, ...
Solution:

To detect the sequence (1,0,1) in the given input data, we need to compare each triplet of inputs with the sequence. If a match is found, the output will be 1; otherwise, the output will be 0.

Let's go through the input data step by step and compare each triplet with the sequence:

1st triplet: (1,1,0)
- No match with the sequence (1,0,1)
- Output: 0

2nd triplet: (1,0,1)
- Match with the sequence (1,0,1)
- Output: 1

3rd triplet: (0,1,0)
- No match with the sequence (1,0,1)
- Output: 0

4th triplet: (1,0,0)
- No match with the sequence (1,0,1)
- Output: 0

5th triplet: (0,0,1)
- No match with the sequence (1,0,1)
- Output: 0

6th triplet: (0,1,1)
- No match with the sequence (1,0,1)
- Output: 0

7th triplet: (1,1,0)
- No match with the sequence (1,0,1)
- Output: 0

8th triplet: (1,0,1)
- Match with the sequence (1,0,1)
- Output: 1

9th triplet: (0,1,0)
- No match with the sequence (1,0,1)
- Output: 0

10th triplet: (1,0,1)
- Match with the sequence (1,0,1)
- Output: 1

11th triplet: (0,1,1)
- No match with the sequence (1,0,1)
- Output: 0

12th triplet: (1,1,0)
- No match with the sequence (1,0,1)
- Output: 0

Therefore, the output of the sequence detector for the given input data is: 0,1,0,0,0,0,0,1,0,1,0,0, which matches option 'B'.

Explanation:

- The sequence detector is designed to detect the sequence (1,0,1) in the input data.
- We compare each triplet of inputs with the sequence, and if a match is found, the output is 1; otherwise, the output is 0.
- In the given input data, the sequence (1,0,1) occurs at the 2nd and 10th positions.
- So, the output of the sequence detector will be 1 at those positions and 0 at all other positions.
- The correct answer option is 'B' which matches the output sequence we obtained.

A sequence detector is designed to detect precisely 3 digital inputs, ...
A sequence detector is a sequential circuit that outputs 1 when a particular pattern of bits sequentially arrives at its data input.
Given input data = 1,1,0,1,0,0,1,1,0,1,0,1,1,0
Overlapping sequences detectable.
The below table shows the output for each sequence.


The output = 0,1,0,0,0,0,0,1,0,1,0,0
