- Manchester encoding guarantees frequent clock synchronization by changing signal values. What is the maximum number of bits which may be encoded without a signal change? (Note: The way this question has been asked. you are not to include the bit which includes a signal change in your count)6. You have received the following 7+4 bit Hamming encoded messages (the Hamming bits are underlined): (b) 11111010110 Assume the messages have been corrupted by at most single bit errors per symbol. Construct tables with the data and redundancy bits and correct the messages if necessaryThe erroneous data and control bits were received as 1110101 with a 1 bit error. This format uses D4 D3 D2 C3 D1 C2 C1 where Ds are data bits and Cs are control bits. Find the original error free 4 bit data by VENN diagram. (help: place the bits as shown in the figure. Numbers are bit positions starting from the right). You have to show your solution steps.
- In the steps of “Append the padding bits” in SHA-512 system (shown in Figure 1), the message is padded so that its length is congruent to 896 mod 1024 or (length ≅ 896 mod 1024). State the value of the following padding field is the message length is: a) 1919 b) 1920 c) 2942Using the Hamming code algorithm (7, 4), convert a data message (0101) using 7bit. Inject an error (o or 1) at position 3 and identify the error position.The number 12.410 is to be written using the closest 8-bit unsigned binary representation. i.Show, using a table of column weightings, that 1100.01102 represents the decimal value 12.37510. ii.Show, using a table of column weightings, that 1100.01112 represents the decimal value 12.437510. iii.Using your results from (i) and (ii) write down the 8-bit unsigned binary number and its decimal equivalent that gives the best approximation to 12.410. iv.Write the decimal number you wrote down in (iii) as a percentage of 12.4. Write your final answer as a percentage rounded to two decimal places.
- 5. You have received the following 7+4 bit Hamming encoded message (the Hamming bits are underlined): 10010110001 10101101111 Assume the message has been corrupted by at most single bit errors per symbol. Correct the message if necessary.3. (b) A sender needs to send the four data items 0x1236, OXABCC, OX03BC, and OXEEEE. To avoid confusion, Ox is written in the prefix to denote that the data is in Hexadecimal. For example, Ox3456 is 3456 in hexadecimal. Now answer the following: i. Find the checksum at the sender site. ii. Find the checksum at the receiver site if there is no error.If we use the 128-bit binary field extension F 128 to decode the 127-bit binary BCH code at a distance of 6, we get a total of 127 bits. How large is the code, and is there a minimum distance you can guarantee?
- Q2. Find out the bit pattern of hamming code considering data bits="11011011". Also explain the phenomenon of error correction considering the 5rd bit (from the left) got inverted during transmission.An 8-bit byte with binary value 10101111 is to be encoded using an even-parity Hamming code. What is the binary value after encoding? ANS: The encoded value is 101001001111 Why is this answer longer from binary value? Please solve this question with details. Please explain why you use that method.Assume that the following block of 16 bits is to be sent using a checksum of 8 bits. What is the pattern (codeword) sent? The block 0f 16 bits is 10101001 00111001.
