Output:-
Enter the total number of symbols:3
Enter the probablities:- .3 .3 .4
Sum is 1.000000
I[0]=l.736966 Bits
I[1]=1.736966 Bits
I[2]=1.321928 Bits
H[0]=0.521090 Bits/Message
H[1]=0.521090 Bits/Message
H[2]=0.528771 Bits/Message
Enter the rate r:1000
Information rate is 1570.950562 Bits/Seconds.
