Parity check codes with even parity can be viewed as linear block codes. Consider the Following situations: a. One parity check bit (even parity) is appended to three data bits. Write down the generator matrix and the parity matrix for this linear block code. b. 2-D even parity for a block of data: di d2 P1 dz d4 P2 P3 P4 Ps where d;'s are the data bits and p;'s are the parity check bits for the rows and the columns. Write down the generator matrix and the parity check matrix for this code. How many errors can it correct? How many errors can it detect?
