+> [!Definition]
+> 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^[1]
 
+- 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 ($Q\ =\ A+\ B$) 
+- Using graphical symbols
+
+
+# Notable Examples
+- [1 Bit half adder](https://i.imgur.com/mjCVU4I.png)
+- [1 Bit full adder: (includes carry input)](https://i.imgur.com/yu6kS83.png)
+- [Ripple carry adder](https://i.imgur.com/HtEIZ5t.png)
+- 3 Bit 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
