Additional guidance information
Your
responsibility
It is your responsibility to read and understand the University regulations
regarding conduct in assessment.
Please pay special attention to the assessment regulations (section 4) on
Academic Misconduct.
In brief: ensure that you;
1. DO NOT use the work of another student – this includes students from
previous years and other institutions, as well as current students on the
module.
2. DO NOT make your work available or leave insecure, for other students to
view or use.
3. Any examples provided by the module tutor should be appropriately
referenced, as should examples from external sources.
Further guidance can be found in the SCEN Academic Skills Resource and UoH
Academic Integrity Resource module in Brightspace.
If you experience difficulties with this assessment or with time management,
please speak to the module tutor/s, your Personal Academic Tutor, or the
School’s Guidance Team. (sce.guidance@hud.ac.uk).
Late
Submission
You are reminded to ‘back-up’ your work as late submission requests will not
be given for lost work, which includes work lost due to hardware and software
failure/s.
Requests for late submission will only be approved if you can demonstrate
genuine, unexpected circumstances along with independent supporting
evidence (e.g. medical certificate) that may prevent you submitting an
assessment on time.
Submit your request for late submission via MyHud/MyStudies within 2
working days of the due date.
Late submission, up to a maximum of 10 working days, but typically 1-5 working
days, will be considered provided that there is appropriate evidence which
clearly indicates reasons for the request.
You will have 5 working days after submitting a request to provide the
evidence. Failure to submit evidence will result in the request being rejected
and your work being marked as a late submission (see below).
If you are unable to submit work within the maximum late submission period of
10 days, contact the School’s Guidance Team. (sce.guidance@hud.ac.uk), as
you may need to submit a claim for Extenuating Circumstances (ECs).
Additional guidance information
Extenuating
Circumstances
(ECs)
An EC claim is appropriate in exceptional circumstances, when an extension is
not sufficient due to the nature of the request, or it concerns an examination or
In-Class Test (ICT).
You can access the EC claim form on the Registry website; where you can also
find out more about the process.
You will need to submit independent, verifiable evidence for your claim to be
considered.
Once your EC claim has been reviewed you will get an EC outcome email from
Registry. If you are unsure what it means or what you need to do next, please
speak to the Student Support Office – Room SJ1/01
An approved EC will extend the submission date to the next assessment period
(e.g. July resit period).
Late
Submission
(No ECs
approved)
Late submission, up to 5 working days, of the assessment submission deadline,
will result in your grade being capped to a maximum of a pass mark.
Submission after this period, without an approved extension, will result in a 0%
grade for this assessment component.

Assessment Brief
This is an individual assignment
When the source at the input of a two-port network has a noise temperature of 290K (which
is very often at least approximately the case) then the noise factor of a two-port network
can be defined as the ratio of the signal to noise ratio (S/N) at the input of the network to
the S/N at the output of the network. Thus:
Where: the S/N are power ratios.
The noise figure is the noise factor expressed in dB. So,
10 ( ) 10log F dB f =
For a cascaded network, the overall noise figure, ftot, can be found using Friis’ formula:
