(Lec-60) Line Coding | Unipolar Scheme | NRZ vs RZ | Data Communication Bangla Tutorial

#LineCoding It is the process used to convert digital data to digital signals. Let us assume that data is in the form of text, numbers, audio, or video and it is stored in the form of a sequence of bits in the computer. Thus Line coding process converts the sequence of bits to a digital signal. On the sender side, the digital data are encoded into digital signals, and on the receiver side, digital data is recreated by decoding the digital signal. #UnipolarScheme In this line coding scheme, all the signal levels are on one side of the time axis. It can be either Above or Below. Basically, Unipolar Scheme was designed as a Non-Return-to-Zero(NRZ) scheme where positive voltage defines bit 1 and zero voltage defined bit 0. The unipolar scheme makes uses only one voltage level. It is called NRZ because the signal does not return to zero in the middle of the bit. 0:00 - Introduction 0:30 - Line Coding 4:30 - Unipolar Scheme 8:30 - NRZ vs RZ 10:15 - Upcoming Topics Data Communications and Computer Networks full playlist:    • Data Communication Bangla Tutorial (Behrou...   Our other completed playlist are : 1.
