Summary

This chapter developed the core ideas of combinational logic design through analysis and experiments on multiplexers/decoders, adders, and an ALU:

• Combinational outputs depend only on current inputs.
• Complex functions can be built hierarchically from basic gates.
• Data selection, arithmetic, and logic operations are fundamental datapath behaviors.

In the next chapter, we will introduce sequential logic (latches, flip-flops, registers) and study clocked state holding and updates, including a finite state machine experiment.
