What we have learnt
- Multiplexers select binary data from multiple inputs based on selection lines and pass them to a single output.
- Demultiplexers perform the reverse operation of multiplexers by routing data from one input to multiple outputs.
- Multiplexers can implement Boolean functions, aiding in the design of complex logic circuits.
Key Concepts
-
Term: Multiplexer (MUX)
Definition: A combinational circuit that selects one of many data inputs and forwards the selected input to a single output line.
-
Term: Demultiplexer (DEMUX)
Definition: A combinational circuit that takes a single input and channels it to one of several outputs based on selection lines.
-
Term: ENABLE Input
Definition: Control input used in multiplexers and demultiplexers to enable or disable the device operation.
-
Term: Boolean Function Implementation
Definition: The process of using multiplexers to realize a specific logical function through the configuration of their input lines according to the function's truth table.
