Logic Gates (XOR & XNOR Gate) - Unit 23: Digital Electronics- Class 12

Logic Gates (XOR & XNOR Gate) - Class 12 Physics - Unit 23 Digital Electronics Master the concept of Exclusive Logic Gates (XOR & XNOR Gates) in Class 12 Physics (Unit 23: Digital Electronics) according to the Board of Intermediate Education Karachi (BIEK) syllabus. In this 3rd and final part of the Logic Gates lecture series, Sir Talha explains the working principle, Boolean expressions, logic circuit diagrams, and step-by-step truth tables (for 2-input, 3-input, and 4-input configurations) using simple odd/even parity concepts. 🌐 Study Notes & Lecture Resources: Access complete unit notes, solved numericals, and board preparation material on our official website: 🔗 Class 12 Physics - Unit 23 Digital Electronics Notes: https://talhaphysicsacademy.blogspot.... --- 📌 Timestamps / Chapters: 00:00 - Introduction & Recap of Logic Gates Series 00:00:32 - Exclusive-OR (XOR) Gate Definition & Odd Parity Rule 00:02:05 - Boolean Expression & Representation of XOR Gate 00:03:51 - Logic Symbol & Internal Circuit Diagram of XOR Gate 00:05:43 - Truth Table Derivation for 2-Input XOR Gate 00:08:42 - Truth Table Analysis for 3-Input & 4-Input XOR Gates 00:10:27 - Exclusive-NOR (XNOR) Gate Definition & Even Parity Rule 00:11:13 - Boolean Expression & Logic Symbol of XNOR Gate 00:12:43 - Truth Table Derivation for 2-Input XNOR Gate 00:15:08 - Truth Table Analysis for 3-Input & 4-Input XNOR Gates --- 📚 What You Will Learn in This Video: • Exclusive-OR (XOR) Gate: Why it yields a HIGH output (1) only when an odd number of inputs are HIGH. • Exclusive-NOR (XNOR) Gate: How adding a NOT gate to XOR produces a HIGH output (1) when an even number of inputs are HIGH (including zero). • Circuit Construction: Building XOR and XNOR logic circuits using basic gates (AND, OR, NOT). • Multi-Input Logic Analysis: Shortcut parity rules to instantly evaluate 3-input and 4-input truth tables in board exams. --- #LogicGates #XORGate #XNORGate #DigitalElectronics #Class12Physics #TalhasPhysicsAcademy #KarachiBoardPhysics #BIEKPhysics #SindhBoardPhysics #PhysicsClass12 #ElectronicsClass12 --- Logic Gates Class 12 Physics, XOR Gate and XNOR Gate class 12, Unit 23 Digital Electronics Class 12, Class 12 Physics Karachi Board, XOR Gate working principle and truth table, XNOR Gate working principle and truth table, Exclusive OR and Exclusive NOR Gate explained, Truth table for 2 3 4 input XOR gate, Boolean expression for XOR and XNOR gate, Logic gates class 12 Sindh Board, Talhas Physics Academy, BIEK Class 12 Physics Unit 23, Class 12 Physics Karachi Board exam preparation, Digital electronics class 12 Urdu Hindi lecture, Logic gate circuit diagram class 12
