What is the definition of a linear block code? q10-4 (2 parts )in a codeword, we add two redundant bits to each 8-bit word. find the number of a. valid codewords& b. invalid codewords q10-6 if we want to be able to detect 2-bit errors, what should be the minimum hamming distance? q10-8 in crc, if the dataword is 5 bits and the codeword is 8 bits, how many os 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? q10-10 in crc, which of the following generators (divisors) guarantees the detection of an odd number of errors? a. 10111 b. 101101 c. 111
