Line Coding Technique in Digital Transmission | Data Communication | Lecture 53 | Urdu | Hindi
Line Coding Techniques in Digital Transmission | Data Communication | Lecture 53 | Urdu | Hindi
Welcome to *Lecture 53* of the *Data Communication* course. In this lecture, we explore **Line Coding Techniques**, one of the most important topics in digital transmission and computer networking.
*Line coding* is the process of converting digital data (bits) into digital signals that can be transmitted over a communication channel. Different line coding techniques provide different levels of synchronization, bandwidth efficiency, error detection capability, and signal reliability.
In this lecture, you'll learn what line coding is, why it is needed, the characteristics of an effective line coding scheme, and an introduction to popular techniques such as **NRZ (Non-Return-to-Zero)**, **RZ (Return-to-Zero)**, **Manchester Encoding**, and **Differential Manchester Encoding**.
This lecture provides the foundation for understanding digital transmission, signal encoding, data communication protocols, and computer networking.
This course is specially designed for *Virtual University (VU)* students studying **CS601 (Data Communication)**, **CS602 (Computer Networks)**, **CS609 (System Programming)**, as well as students of **BS Computer Science (BSCS), Software Engineering (BSSE), Information Technology (BSIT), Computer Engineering, Electronics Engineering, Electrical Engineering**, and similar undergraduate programs offered by universities worldwide.
