Digital Logic 04 | Combinational Circuit | Comparator | CS, IT & EE, ECE | GATE Crash Course

This video, Digital Logic 05, is an essential part of the GATE Crash Course focusing on key Combinational Circuits, a critical topic for CS, IT, EE, and ECE branches. The lecture is divided into two major sections: first, a detailed explanation of the Digital Comparator (like the 2-bit and 4-bit comparator), covering its logic and truth table to determine.The second, and perhaps most crucial, part covers the Multiplexer (MUX), often called a data selector. You will learn the working principle, expression, and implementation of MUXes and more importantly, how to implement any Boolean function using a MUX—a very common type of question in the GATE exam. 📕 𝐁𝐚𝐭𝐜𝐡/𝐂𝐨𝐮𝐫𝐬𝐞 𝐋𝐢𝐧𝐤𝐬:- GATE GURUKUL Course Link - https://www.geeksforgeeks.org/courses/gate-premium All courses - https://www.geeksforgeeks.org/courses/category/gate?utm_source=youtube&utm_medium=livestreams&utm_campaign=gatelivesessions GATE Agni Pariksha Batch Link - https://www.geeksforgeeks.org/payments/gate-cse-agni-pariksha GATE 2026 CS & IT Test Series Link - https://www.geeksforgeeks.org/courses/gate-cse-it-test-series-2026 GATE 2026 DA Test Series Link - https://www.geeksforgeeks.org/courses/gate-da-testseries-2026 Mission ISRO CSE - https://www.geeksforgeeks.org/courses/mission-isro-cse Mission ISRO ECE - https://www.geeksforgeeks.org/courses/mission-isro-ece GATE SPL.
