Lecture Notes

Students are responsible for the material in the textbook and that in the handouts, if any. The class notes and slides are just "notes"; they may not cover all required material. The book is the reference for the required material.

Below are a set of electronic class notes that are based on the textbook.

Chapter 1: Data Communications and Networking Overview

Chapter 2: Protocols - The OSI Reference Model and the TCP/IP Stack

Chapter 3: Fourier Analysis - These slides are still under development - not final.

                In addition you can refer to the following handout:  Fourier Series Expansion and Filtering

               Data, Signals and Transmission

Chapter 4: Transmission Media 

             These slides are originally for Stallings - I just added some explanatory text and modern (colored) illustrations

Chapter 5: Data Encoding -  Modulation Techniques

                 Animation for PCM (the animations were provided by Forouzan)

Chapter 6:  Digital Data Communication Techniques: Asynchronous/synchronous Transmission, Error Detection, and Error Coding (optional)

Chapter 7: Data Link Control (Flow/Error Control Schemes and HDLC) - ARQ design problems.

                Animations for: stop-and-wait protocol, sliding-window protocol, CRC calculation, and HDLC (the animations were provided by Forouzan)

Chapter 8: Multiplexing (FDM and TDM)

                Animations for: FDM, TDM, and Statistical TDM  (the animations were provided by Forouzan)

These are the set of notes provided by the publisher. The original power point files are found at: ftp://ftp.prenhall.com/pub/esm/computer_science.s-041/stallings/Slides/DCC6e-Slides/

Handouts:

• Handout on Fourier Series Expansion and Filtering: This handout attempts to explain the following concepts using an example:

1. Periodic signals - Period T and the relationship with the fundamental frequency f
2. The DC component of a signal - The power of a periodic signal
3. The Fourier series expansion of a periodic signal
4. Computing the power of a signal using its Fourier series expansion - Computation of power of truncated signals
5. Low/Band/High pass filtering (ideal)
6. Introduces MATLAB programming language (code included in document)
