1.	A source generates three symbols with probabilities 0.25, 0.25, 0.50 at a rate of 3000 symbols per second. Assuming independent generation of symbols, the most efficient source encoder would have average bit rate is as
Answer» Use Shannon Fano coding. (0.25) is encoded as 01 Number of bits/sec = 0.25 x 3000 x 2 + 0.25 x 3000 x 2 + 0.5 x 3000 45000 bits/sec.
