Question 3
|
Which of the following is true?
|
Both Parity and Cyclic Redundancy Check are error correcting codes
|
|
|
Both Parity and Low Density Parity Check Code are error correcting codes
|
|
|
Both Reed-Solomon code and Low Density Parity Check Code are error correcting codes
|
|
|
Both Cyclic Redundancy Check and Low Density Parity Check Code are error correcting codes
|
Question 3 Explanation:
Reed-Solomon Code: Reed-Solomon codes are widely used error-correcting codes, especially in applications where burst errors are common, such as in data storage systems (CDs, DVDs, QR codes, etc.). They can correct multiple errors and are known for their effectiveness in dealing with errors in communication.
Low Density Parity Check Code (LDPC): LDPC codes are also error-correcting codes. LDPC codes have gained popularity, especially in modern communication systems, for their capacity to approach the Shannon limit for channel capacity.
Low Density Parity Check Code (LDPC): LDPC codes are also error-correcting codes. LDPC codes have gained popularity, especially in modern communication systems, for their capacity to approach the Shannon limit for channel capacity.
Correct Answer: C
