Step 1: Understanding the Concept:
CRC uses polynomial division where bits are treated as coefficients. To find the CRC remainder, we append zeros to the data (where is the length of the generator) and perform binary (XOR) division.
Step 2: Key Formula or Approach:
Generator = 1001 (length 4).
Append zeros to the data bits: 110001011000.
Step 3: Detailed Explanation:
Perform binary division (XOR subtraction):
Step 4: Final Answer:
The remainder is 100, which is option (B).
