- In a codeword, we add two redundant bits to each 8-bit data word. Find the following: Number of valid codewords , Number of invalid codewords. - If we want to be able to detect 2-bit errors, what should be the minimum Hamming distance? - In CRC, if the dataword is 5 bits and the codeword is 8 bits, how many 0s need to be added to the dataword to make the dividend? What is the size of the remainder? What is the size of the divisor?
