Given a message of 11001001, which polynomial could be used to protect it using CRC? A) x + 1 B) x^4 + 1 C) x^3 + 1 D) x^2 + 1
Understand the Problem
The question is asking which polynomial can be used to protect the given binary message using CRC (Cyclic Redundancy Check). This involves understanding CRC principles and evaluating the options provided.
Answer
x^3 + 1
The final answer is x^3 + 1
Answer for screen readers
The final answer is x^3 + 1
More Information
The polynomial x^3 + 1 is suitable for detecting errors in message transmissions, making it an effective choice for the CRC process in this context.
Tips
Ensure that when choosing a polynomial for CRC, it is capable of detecting common types of errors such as single-bit errors, double-bit errors, and burst errors. More complex polynomials typically provide better error detection capabilities.
