Construct 16-to-1 line multiplexer with two 8-to-1 line multiplexers and one 2-to-1 line multiplexer. Makes suitable assumptions, if any 5m Dec2005

 Multiplexer

Multiplexer is one of the basic building units of a computer system which in principle allows sharing of a common line by more than one input lines. It connects multiple input lines to a single output line. At a specific time one of the input lines is selected and the selected input is passed on to the output line.

                               Relation between multiple Input lines and Selection lines      

 

Input lines 16 = 24 i.e. 4 Selection lines

Input lines will be I0 - I15

 

Selection lines will be S0 - S3

Block Diagram:

MUX_02

Constructed Diagram:

MUX_01

The diagram will be same as of the block diagram of 16-to-1 line multiplexer in which 8-to-1 line multiplexer Selection lines will be S0 - S2and S3will be connected to 2-to-1 line multiplexer Selection and First 8-to-1 line multiplexer Input lines will be I0 - I7and Second8-to-1 line multiplexer Input lines will be I8 - I15
