Consider a SEC code that protects 8-bit words with 4 parity bits. If we read the value0xABC, is there an error? If so, correct the error.Note: 0xABC = 1010 1011 1100Hint: Decode the 12-bit encoded data and find if there is an error.
Consider a SEC code that protects 8-bit words with 4 parity bits. If we read the value OxABC, is there an error? If so, correct the error. Note: 0xABC = 1010 1011 1100 Hint: Decode the 12-bit encoded data and find if there is an error. Hint 2: You can use the table below. The values of the data already inserted. Note that, you don't have to use the table. In case you want to solve it differently, it is fine. 1 2 3 4 5 6 7 8 9 1 0 1 0 1 0 1 1 1 10 1 11 0 12 0
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.
b) Let's say a networking company uses a compression technique to encode the message before transmitting over the network. Suppose the message contains 6 unique characters of your name and their frequencies are similar to the last 6 non-zero digits of your mobile number. For example, your name is Badhon and the last 6 digits of your mobile number is 123456. So the frequency Frequency (in thousands) Characters B table of characters will be: 2 3 H. 4 Now, if the compression technique used is Huffman Coding instead of variable-length coding, how many bits will be saved in the message? Show the saving percentage. 6.
Consider this string 1111100011101100, Spread the string out to make room for parity bits, putting X’s in for the Hamming parity bits, a Y for overall parity, maybe even spaces for clarity.
Detailed and correct answer will be Upvoted. Thank you
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 big is the code, and is there a guaranteed minimum separation?
Provide the explanation for both correct and incorrect option. Asap needed. Irrelevant explanation will be downvoted.
QUESTION1 "Rabenstein code was used to send a message with 4 information bits, you receive 100110001 if you can expect at most one bit of corruption, what were the original information bits?" QUESTION 2 Givon the codeword set 111111 000111 110001 101100 011010 Add another codeword to this set that has distance at least 3 to all other codewords.
In defining the Hamming distance for a code, we choose to usethe minimum (Hamming) distance between any two encodings.Explain why it would not be better to use the maximum or averagedistance.
Fill in the empty spaces in the following table. As you do, please be aware of the following: • All numbers are considered signed (negative) for this table • All binary answers must have 16 bits • You need to put a space after every 4 bits for binary values. All hex values must use capital letters Signed Decimal 16-bit Binary Нех |-12 -20 1111 1111 1110 1100| FFEC 65495 1111 1111 1101 FFD7
