- 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.one way of detecting errors is to transmit data as a block of n rows of k bits per row and adding parity bits to each row and each column. the lower-right corner is a parity bit that checks its row and its column, will this scheme detect all single errors? double errors? triple errors?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.

- 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)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?ASCII Codes can be helpful to find binary code of different decimal numbers and alphabets etc. You have to consider 65 and its equivalent code of 16 bits will be considered for bit sequence and a divisor for CRC. Follow this process; first 8 bits will be used for data while next 4 bits will be used for divisor (if there are 4 zeroes in your case then replace with 1001), neglect last 4 bits. Also check your answer.
- Cs The redundant bit offers a simple error correction. Example The sixth digit in the ISBN 0 – 7923 519 - X has - faded out. We want to find the missing digit.Suppose we are working with an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 7. We have already calculated that we need 4 check bits, and the length of all code words will be 11. Code words are created according to the Hamming algorithm presented in the text. We now receive the following code word: 1 0 1 0 1 0 1 0 1 1 0 Assuming odd parity, is this a legal code word? If not, according to our error-correcting code, where is the error?Suppose we are working with an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 7.
