3. Combinational logic circuits

In the previous chapter, we have presented and realized logic gates out of transistors. Logic circuits, on the other hand, use a combination of gates to realize more complex functions. Logic circuits can be classified as combinational and sequential. In this chapter, we will present combinational logic circuits. A combinational logic circuit is a type of digital circuit where the output is a pure function of the input. In the following subchapters, we will build different combinational logic circuits from gates, in order to explain their behavior. At the very beginning of the chapter, we will round up our paradigm presented in the first chapter, and build a full adder.
