Consider a telegraph source having two symbols, dot and dash. The dot duration is 0.2 second. The dash duration is three times the dot duration. The probability of the dot’s occurring is twice that of the dash, and the time between symbols is 0.2 second. Assume n = 2 ( 2nd extension of the code), pdash = S0 and pdot = S11. Determine the equivalent codeword for each symbol using Shannon Code. Supersymbol Code S0 S0 S0 S1 S1 S0 S1 S1 2. Determine the coding efficiency.

In this and the following question, consider those TMs that satisfy all of the following properties: Q={90,91,9a9r}: there are exactly two states besides the accept state and the reject state. • Σ={1}: the input alphabet has just one symbol. • [={1,_}: the tape alphabet has two symbols, where is the blank symbol. • The head is moved in every step, that is, 8 uses only L and R, but not N. • If the machine is started on the completely empty tape, it will halt after a finite number of steps, that is, it will reach qa or qr. If such a TM is started on the completely empty tape, it will leave a certain number of 1 symbols on the tape after it halts. What is the maximum number of 1 symbols on the tape, among all of these TMs? Answer: Check Consider again the TMs of the preceding question. If such a TM is started on the completely empty tape, it will make a certain number of transition steps. What is the maximum number of steps, among all those TMs? Answer: Check
