Chapter 2.2 of the Data Transmission Lecture by Cao Van Loi provides knowledge on various data encoding methods, including NRZ, RZ, Biphase, Manchester, and HDB3. This document also discusses issues related to data encoding such as using two time instants to encode a bit, changing signal states during transmission, and using different encoding methods for encoding signals.

This document is intended for students, researchers, and professionals in the field of communication technology and digital signal processing.

This chapter of the Data Transmission Lecture by Cao Van Loi focuses on data encoding methods, which is the process of converting signals into a form that can be transmitted through a communication channel. There are several data encoding methods, including NRZ (Non-Return to Zero), RZ (Return to Zero), Biphase, Manchester, and HDB3. The document also discusses issues related to data encoding such as using two time instants to encode a bit, changing signal states during transmission, and using different encoding methods for encoding signals.
