What is Full Adder ?| Learn under 5 min | Adder circuit | Digital Circuit | DE.19

The video begins with a thank you to viewers and a recap of the half adder circuit. It introduces the full adder circuit, explaining its ability to add carry bits from previous additions. The full adder has three inputs (A, B, CI) and two outputs (S, CO). The truth table is discussed, showing when outputs are high. Boolean equations for outputs are derived using K maps. The video explains how to build a full adder circuit using XOR, AND, and OR gates, but notes that integrated circuits are available. It concludes with a call to share the video and subscribe for more content.
