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
6000 bits/sec
4500 bits/sec
3000 bits/sec
1500 bits/sec
Answer: Option
Explanation:

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.
