Weighting
This assignment is worth 40% of the module marks. It is an individual assignment.
Submission of Assessment
Electronic Management of Assessment (EMA): Please note if your assignment is submitted electronically it will be submitted online via Turnitin by the given deadline. You will find a Turnitin link on the module’s eLP site.
The marks will be returned on eLP together with individualised feedback after the assessment submission deadline within 20 working days.
It is your responsibility to ensure that your assignment arrives before the submission deadline stated above. See the University policy on late submission of work.
Instructions on Assessment:
Answer all questions (see end of brief). Show evidence of simulations using LabView by printing your programs. You can submit an electronic copy of your assignment.
Mapping to Programme Goals and Objectives
Intellectual / Professional skills & abilities:
4. A set of 4 experiments in the semester will allow the students to develop their practical skills. Will be assessed in the coursework. (AHEP4, M12)
Module Specific Assessment Criteria and Rubric
The marking scheme is given below.
ASSESSMENT REGULATIONS
You are advised to read the guidance for students regarding assessment policies. They are available online here. You should take particular attention to the Academic Misconduct Policy document in section 3.6, with regards to using Artificial Intelligence Systems in your assignments.
You are reminded that plagiarism, collusion and other forms of academic misconduct as referred to in the Academic Misconduct procedure of the assessment regulations are taken very seriously. Assignments in which evidence of plagiarism or other forms of academic misconduct is found may receive a mark of zero.
Late submission of work
Where coursework is submitted without approval, after the published hand-in deadline, the following penalties will apply.
Assessment Brief
Page 2 of 3
For coursework submitted up to 1 working day (24 hours) after the published hand-in deadline without approval, 10% of the total marks available for the assessment (i.e.100%) shall be deducted from the assessment mark.
Coursework submitted more than 1 working day (24 hours) after the published hand-in deadline without approval will be regarded as not having been completed. A mark of zero will be awarded for the assessment and the module will be failed, irrespective of the overall module mark.
These provisions apply to all assessments, including those assessed on a Pass/Fail basis.
The full policy can be found here.
Students must retain an electronic copy of this assignment (including ALL appendices) and it must be made available within 24hours of them requesting it be submitted.
Word Limit
If the assignment is within +10% of the stated word limit no penalty will apply. The word count does not include: appendices, glossary, footnotes, tables
Please note, in text citations [e.g. (Smith, 2011)] and direct secondary quotations [e.g. “dib-dab nonsense analysis” (Smith, 2011 p.123)] are INCLUDED in the word count.
Students must retain an electronic copy of this assignment (including ALL appendices) and it must be made available within 24hours of them requesting it be submitted.
The full Word Limit Policy is available here.

Assessment 2: Simulating frequency analysis of audio signals encoded using amplitude modulation (LO4)
Problem Statement:
This report is based on the Communication laboratory session. You need to follow the steps and complete the given tasks. Below is a summary of the lab and the tasks you need to accomplish. In this exercise, you will create a LabVIEW virtual instrument (VI) to perform amplitude modulation of an audio signal and then run a frequency analysis of the generated signal.
This is meant to simulate a simplified version of an audio signals encoded device solely for voice communication, using an analogue-based amplitude modulation (AM) scheme (ex: Walkie-Talkie). This means the voice is used to modulate the amplitude of a single frequency carrier wave, which is then directly transmitted to the receiver. At the receiver end (not modelled in this assessment), after demodulation, the voice is detected and played. The reason for the frequency analysis is to work out the central frequency and bandwidth of the transmitted signal to make sure it adheres to UK OFCOM regulations.
Objectives:
As the designer, you need to identify the following parameters:
1
- Required Bandwidth: Record your voice using microphones and analyse its frequency representation to estimate the system’s bandwidth [As seen in the Communication laboratory session] (10%).
2
- Carrier Frequency: Refer to UK OFCOM regulations to find an available frequency band for the system (5%).
3
- Transmit Power: Check UK OFCOM regulations to determine the permissible transmit power (5%).
4
- System Block Diagram: Create a block diagram of the system, including the main fundamental blocks with their parameters (15%).
5
- Block Functions: Explain the function of each block in the diagram (15%).
6
- System Schematic: Design the schematic of the entire system in the simulation software (LabVIEW):
a. Use the correct blocks and wire connections (20%).
b. Comment on the schematic to explain the system (5%).
7
- Simulation: Simulate the system and extract the time domain and frequency domain signals at the output of each block (25%).
The report needs to be submitted as a PDF file with each section clearly specified using the numbers given in the objective section.
