The assignment has two parts:  Part A and Part B.  PART A: Implementation of µ-law and A-law Compander       (40 marks)   Most modern communications systems operate in the digital domain for various reasons. However,  most practical signals handled by these systems are naturally analogue in nature. Thus, an interface is  needed between the signals and the systems handling them. This interface is called analogue-to-digital  converter (ADC) and it’s reciprocal, digital-to analogue converter (DAC). The three main functions of  the ADC are sampling, quantization and encoding.   Requirements  1) Implement nonlinear quantizers µ-law and A-law compander in MATLAB/Simulink and  compare the results. Matlab/Simulink code is required to be included in the report.  2) Prepare a report incorporating theories behind non-uniform quantization. Report should  include comparison result and its interpretation from the simulation.  PART B: Source Coding in Digital Audio Systems      (50 marks)   Digital audio has become an integral part of our lives. Nearly all of the transmission of speech signals  over telephone channels is currently digital. Moreover, digital audio recording in the form of compact  disks (CDs) has become very popular. This assignment exposes the student to real world applications  of digital communication in digital audio transmission and recoding. Therefore, the student shall  acquire skills to understand the real world requirements, critically review the existing techniques and  write a technical report based on his or her investigation.  Requirements   The student needs to address the following three areas:   1) a) Requirement analysis: student is required to analyze the following for digital audio in  telephone transmission systems:    Bandwidth of speech signals and the required sampling rates to avoid aliasing   Required number of bits per sample to achieve voice quality in telephony  ME502 Overview of Digital Communication  Page 3 of 5     Lasted Updated: March 2019 b) In addition, student is also required to analyze the following for digital audio recording:   Bandwidth of high quality audio and the required sampling rates   Required number of bits per sample to achieve a high signal to quantization noise level for  high quality audio. 2) Investigation of current methods: student is required to review and analyze waveform-coding  techniques used in digital audio transmission and recording at present. At least PCM and  DPCM methods need to be covered. Marking criteria For Part A:   Marks are allocated as follows: Section to be included  in the report   Description of the section  Marks   MATLAB   programming  competence   Does student demonstrate competence in  programming in MATLAB? Does the code run?  Does the code solve the intended problem?   15   Non-uniform  quantization. competence   Does student demonstrate the ability to  implement a function in a digital communication  system in software?   5   Competence in modern  technology   Does student demonstrate the understanding of  non-uniform quantization, and Why is it needed  to be used in digital communications?   5   Critical reflection  Does the report demonstrate reflection and  understanding of the topic or it was hastily  written?   5   Research depth Does the student work demonstrate that the  student consulted additional referenced materials  on the topic and used the IEEE referencing style  well?   5   ME502 Overview of Digital Communication  Page 4 of 5     Lasted Updated: March 2019  English grammar and  coherence, and  professional report  writing   Does the question posted contain good English,  good grammar, admirable writing style, no typos,  good format, etc.? Is the report void of cut-and- paste figures and tables? Are all graphics  captioned and referenced appropriately in the  report?   5   Plagiarism  Did the student do any of these without  reference and reflection? - Copy from other  student(s)   - Copy from Internet source/textbook   - Copy from other sources   -40 For Part B: Marks are allocated as follows: Section to be included  in the report   Description of the section  Marks   Requirements   Requirement analysis for digital audio transmission and  recoding   25   Current practices  Literature review of the current waveform coders  covering at least PCM and DPCM   20   Reference style   IEEE referencing style 5   Poor writing  Inadequate structure, careless presentation, or the report  exceeds the word limit by more or less than 10%   -10   Plagiarism  Type of plagiarism   - Copy from other student   - Copy from internet source/textbook   - Copy from other sources   -50 ME502 Overview of Digital Communication  Page 5 of 5     Lasted Updated: March 2019  Marking Rubric: Grade  Mark  HD  80%+  D  70%-79%  CR  60%-69%  P  50%-59%  Fail
