In 1-to-4 demultiplexer, how many select lines are required?(a) 2(b) 3

1.	In 1-to-4 demultiplexer, how many select lines are required?(a) 2(b) 3(c) 4(d) 5I have been asked this question during a job interview.I'd like to ask this question from Demultiplexers (Data Distributors) in section Combinational Circuits of Digital Circuits
Answer» Correct answer is (a) 2 For explanation I WOULD say: The formula for TOTAL no. of OUTPUTS is given by 2^n, where n is the no. of SELECT lines. Therefore, for 1:4 demultiplexer, 2 select lines are required.
