De-multiplexer

1. DE-MULTIPLEXER

2. What is de-multiplexer? Demultiplex (DEMUX) is the reverse of the multiplex (MUX) process – combining multiple unrelated analog or digital signal streams into one signal over a single shared medium, such as a single conductor of copper wire or fiber optic cable. Thus, demultiplex is reconverting a signal containing multiple analog or digital signal streams back into the original separate and unrelated signals.

3. Types of de-multiplexer 1-to-2 (1 SELECT LINE) 1-to-4 (2 SELECT LINES) 1-to-8 (3 SELECT LINES) 1-to-16 (4 SELEC T LINES) A DE-MULTIPLEXER has: - N control inputs - 1 data input - 2 to the power N OUTPUT A de-multiplexer routes(or connects) the data input to selected output. - The value of the control inputs determines the output that is selected.

4. 1-to-2 (1 select line)

5. 1-to-4 (2 select line)

6. 1-to-8 (3 select lines)

7. 1-TO-16 (4 SELECT LINES)

8. Typical application of de-multiplexer De- multiplexer is used to connect a single source to multiple destinations. The main application are of the de-multiplexer is communication system where multiplexer are used. communication System ALU (Arithmetic Logical unit) Serial to parallel converter
