subject: Data Communication (CSE). its just a final question . if any need info i have just lecture slide thats it.

1. (a) Explain the effect of adding more redundant bits in error detection. [01] (b) Generate the simple parity check code of 3B/4B and from this scheme prove [02] that d min = 2 [02] ao a (e) In the hamming code C (7,4), three redundant bits are generated as follows: ? = a 2 a ri = a 3 r2 az a Sender sends the codeword 0111001 and the receiver receives the codeword 0101001. How this error can be detected and corrected? 2 di = 1. (a) Explain the effect of adding more redundant bits in error detection.
