In-class Exercises2 10 points 1. Assume RAC (Row And Column) parity matrix is the error checking method and even parity is used. To send 1001 1011 0100 using a 4 by 5 matrix (8 parity bits). give the matrix to be sent below is there any error in it, if yes how to correct it? 1 0 0 11 1 0 O 2. To send a data word: D-1010, x xusing CRC for error checking with the div a) Design the hardware for this G(x) T- x 1010 ooo G(x): 1011 bit 3 bit 1 input bit 2 b) Perform binary division for CRC, circle the remainder, and give the code word to be sent. Data word: D=1010 G-1011 1011 1 01 oO O O the code word to be sent Remainder- , Assume a receiver get another code word: 110110110 Q: Is there an error in it? 1011 1101 1 0 1 1 o
