Combines several signals into one
|
|
|
|
Consists of
|
|
* An output
|
|
* _n_ inputs,
|
|
* log,,2,,(_n_) selectors
|
|
|
|
This alone allows us using the selectors, to choose which input
|
|
|
|
This is best shown with a 2 input multiplexer, which only needs 1 selector

|
|-----|--------|
|
|
| 0 | in0 |
|
|
| 1 | in1 |
|

|
And thats all there is to it. This scales up with several inputs,
|
|
several selectors, and one output
