* A coin is tossed twice, so the probability at least one head occurred is 0.5 O 0.99 0.75 0.25 O Calculate the fixed code efficiency for the following symbols P(A)=12. *P(B)=1/4. P(C)=P(D)=18. H=175 0.757 O 0.999 0.875 0.9333 O A source puts out one of five possible messages during each message interval. The probabilities of two of them are (mi, m2] P1 = 1/32. P2 = 1/64. * ? What is the information content of these messages in bit (m1) -5 bits and I (m2) =6 bits O (m1) =6 bits and 1 (m2) =5 bits (m1) -4 bits and 1 (m2) =6 bits (m1) =6 bits and 1(m2) =4 bits O Q3/(MCQ) Chose the correct answers for the following: (20 points) Calculate the average code word length for the following symbols P(A) = *0.5. P(B)=0.3. P(C)= 0.2. Code(A)=00, Code (B) =11. Code (C)=010 1.1 O 2.2 3.3 O 3 O for Uniform distribution P(xi)= 1/N = 1/128 find the average information * (H(xi)) 7 bits/sample o 6 bits/sample 5 bits/sample 8 bits/sample O
