The fixed length code of the "ABBAD" is: 2 points (00010010100) (000001001000011) At least two codes are correct (011001) Using the variable length code increases the number of bits. 1 point True False For the codeword length n1 = n2 s... SnL, the Kraft Inequality $ 1. 1 point True O False 1 point Consider a source X which generates four symbols with probabilities P1 = 0.5, P2 = 0.3, P3 = 0.1 and P4 = 0.1 for the codes (0, 10, 110, 111). The efficiency of the coding systems is: 0.9912 90% 1.7 bits 0 1 The average codeword length of the above question is: 1 point 1.7 bits O 1.5 bits 0.5 bits 2 bits
