I. Complete the given table by writing the source encoded message of the following set of directions. Set of Directions Source Encoding LEFT - UP - RIGHT - DOWN 1.) UP - DOWN - UP - RIGHT 2.) DOWN - DOWN - RIGHT - LEFT 3.) UP - DOWN - LEFT - RIGHT 4.) RIGHT - LEFT - RIGHT - UP 5.) II. Decode the set of directions given by the message received. Message Received Decoded Message 10010011 1.) 01010010 2.) 11000110 3.) 01100111 4.) 00101111 5.) III. Complete the given table by writing the channel encoded message by using parity check of adding 1 bit in the message. Message Source Encoding Channel Encoding ALLY 000 1.) ENEMY 011 2.) ATTACK 100 3.) RETREAT 111 4.) SURRENDER 101 5.)
ACTIVITY : CODING
Suppose the following messages are source encoded given by the table.
Message Encoded Bits
UP 00
DOWN 01
LEFT 10
RIGHT 11
