Q3.Consider (7,4) cyclic code with g(x)=1+x+x3, a) Draw the block diagram of the cyclic encoder with 1010 as a message, b) Design a syndrome calculator for the received data [1010101] and calculate the syndrome for the received data. Q4. Find the systematic and non-systematic code word of (7,4) using generator polynomial matrix for the message [1011] if the generator polynomial is g(x)=1+x+x3
