There are now 3 possible online modes for units:
Units with modes Online timetabled and Online flexible are available for any student to self-enrol and study online.
Units available in Online Restricted mode have been adapted for online study only for those students who require the unit to complete their studies and who are unable to attend campus owing to exceptional circumstances beyond their control. To be enrolled in a unit in Online Restricted mode, students should contact their Student Advising Office through askUWA

100% Online Unit. NO campus face-to-face attendance is required to complete this unit. All study requirements are online only. Unit is asynchronous delivery, with NO requirement for students to participate online at specific times.
100% Online Unit. NO campus face-to-face attendance is required to complete this unit. All study requirements are online only. Unit includes some synchronous components, with a requirement for students to participate online at specific times.
Not available for self-enrolment. Students access this mode by contacting their student office through AskUWA. 100% Online Unit.
NO campus face-to-face attendance. All study and assessment requirements are online only. Unit includes some timetabled activities, with a requirement for students to participate online at specific times. In exceptional cases (noted in the Handbook) students may be required to participate in face-to-face laboratory classes when a return to UWA’s Crawley campus becomes possible in order to be awarded a final grade.
No attendance or regular contact is required, and all study requirements are completed either via correspondence and/or online submission.
Regular attendance is not required, but student attends the institution face to face on an agreed schedule for purposes of supervision and/or instruction.
Multiple modes of delivery. Unit includes a mix of online and on-campus study requirements. On campus attendance for some activities is required to complete this unit.
MECH4424 Measurement and Noise
- 6 points
Availability Location Mode Semester 2 UWA (Perth) Face to face Semester 2 Online Online timetabled
- This unit covers concepts relating to measurement and noise, enabling students to understand the issues required to achieve high-quality measurements. Students understand issues such as accuracy, precision, repeatability, calibration, uncertainty and noise. Measurements from a range of sensors (mechanical, optical, electrical) are introduced and subsequent signal conditioning (operational amplifiers, instrumentation amplifiers) are addressed with the aim of maximising signal quality. Statistical methods are discussed to better understand noise processes and how noise can be minimised. Methods to improve signal quality (signal to noise ratio) are discussed. Measurement signal and noise are analysed in both the time and frequency domain to better understand the connection between two domains and the importance of measurement bandwidth. Sampling is reviewed to understand the impact of moving from continuous-time (CT) and discrete-time (DT), including discussion of the Nyquist rate and aliasing. The conversion between the analogy to digital domains including CT-DT, system transfer functions, spectral analysis (discrete Fourier transform, discrete-time Fourier transform) and the construction of finite and infinite impulse response filters to reduce noise is discussed.
- Students are able to (1) explain measurement concepts ; (2) extract critical information from instrumentation specifications to enable high quality experimental design; (3) achieve high-quality measurements using appropriate collection and data manipulation methods; (4) present data (numerically and in graphical form) in a manner that is clear and concise and includes the uncertainty associated with the measurement; (5) move between the time and frequency domains to interpret measurements and minimise noise; (6) critically assess instrumentation characteristics that affect data collection and measurement; and (7) analyse data in a manner that includes the uncertainty associated with the measurement.
- Indicative assessments in this unit are as follows: (1) laboratories; (2) quizzes; and (3) final examination. Further information is available in the unit outline.Student may be offered supplementary assessment in this unit if they meet the eligibility criteria.
Except where supplementary assessment is not available in a unit, it will be offered to students in all units who:
- Are in good academic standing overall;
- Have passed over half the units taken in the teaching period concerned, except where they are only enrolled in two or less units in the period;
- Have submitted all assessment items in the unit;
- Have achieved a mark between 45 and 49 for the unit overall, or the same mark in any failed component item in the unit; and
- No finding of academic misconduct has been made against them in the unit concerned.
Additionally student may apply for supplementary assessment in any unit which is the final unit required for graduation in there course and where they have achieved a mark between 45 and 49 for the unit overall, or the same mark in any failed component item in the unit.
- Unit Coordinator(s)
- Associate Professor Adrian Keating
- Unit rules
- enrolment in the Bachelor of Automation and Robotics and CITS1001 Software Engineering with Java and ENSC3001 Mechanisms and Machines, or enrolment in the Master of Professional Engineering (Mechanical Engineering specialisation) or the Master of Renewable and Future Energy
- Advisable prior study:
- CITS2401 Computer Analysis and Visualisation and ENSC3001 Mechanisms and Machines
- Contact hours
- lectures/information sessions: 3 hours per week; practical classes: 1 hour per week; labs: 2 hours per week
- It is recommended that students are familiar with the Microsoft Excel spreadsheet program as this program will be used to perform calculations in assessments/labs.
- The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
- All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
- Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
