1.	How many select lines would be required for an 8-line-to-1-line multiplexer?(a) 2(b) 4(c) 8(d) 3The question was asked in examination.Enquiry is from Multiplexers (Data Selectors) in chapter Combinational Circuits of Digital Circuits
Answer» The correct answer is (d) 3 The best I can explain: 2^n input LINES, n control lines and 1 output line available for MUX. Here, 8 input lines mean 2^3 INPUTS. So, 3 control lines are possible. Depending on the STATUS of the select lines, the input is selected and FED to the output.
