|
> Combinatorial Logic Circuit is a circuit whose digital outputs are dependent only on its digital inputs
|
|
They can be described using logic expressions and therefore logic gates. We assume the outputs respond immediately
|
|
|
|
- current flows from + to -
|
|
- input to a unit (e.g., LED) is at the + end
|
|
|
|
They can be defined:
|
|
- Using a truth table
|
|
- Using [boolean-equations](notes/boolean-equations.md) ($Q\ =\ A+\ B$)
|
|
- Using graphical symbols
|

# Parity Generator

Adds an extra bit to the input data so that the number of ones in the output is always odd. Used for error checking
