W7_L1: 2:4 Decoder using 3:8 Decoder | reuse logic to build smaller decoders efficiently
Welcome to Week 7 Lecture 1 of the course "Digital System" by Prof. Janakiraman Viraraghavan

Video Overview
This lecture demonstrates how to build new digital circuits by reusing existing components, a key principle in modular system design. Starting with a 3-to-8 decoder implemented using standard logic gates like AND, OR, and Inverter, we explore how to repurpose this module to construct a 2-to-4 decoder. By fixing one of the inputs and selecting specific outputs, we reduce design effort and improve hardware efficiency. The lecture emphasizes practical techniques for digital circuit implementation and showcases how module reuse simplifies development in larger systems.This video is ideal for anyone learning about digital systems, decoder design, or circuit optimization using reusable components.
