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 = S1 1. 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.
