This unit involves the skills and knowledge required to design and develop digital systems.

It includes designing and developing a digital system. It also includes working safely, following design brief, interpreting device/component specifications, constructing prototype devices, applying programming techniques to programmable devices, testing developed system prototype operation, verifying compliance of the design against the final brief, and documenting design and development work.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

Requests for modifications to the design are negotiated with relevant person/s within the constraints of workplace policy

3.3

Final design is documented and approval obtained from appropriate person/s

3.4

Quality of work is monitored against design brief performance agreement and/or workplace procedures or industry standards

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions on at least two separate occasions and include:

applying relevant work health and safety (WHS)/occupational health and safety (OHS) requirements, workplace procedures and practices, including using risk control measures

applying sustainable energy principles and practices

constructing and testing prototype devices and circuits in accordance with design brief and regulatory requirements

dealing with unplanned events/situations in accordance with workplace procedures in a manner that minimises risk to personnel and equipment

developing outlines of alternative designs

developing the design within the safety and functional requirements and budget limitations

documenting and presenting design effectively

negotiating design alteration requests successfully

obtaining approval for final design

verifying compliance of the design against the final brief.

Evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the elements, performance criteria and range of conditions and include knowledge of:

analogue to digital conversion

connection of test/measuring devices into a circuit

current types of oscillators based on their characteristics and operation

Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment.

Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated suitable workplace operational situations that replicate workplace conditions.

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.

Resources for assessment must include access to:

a range of relevant exercises, case studies and/or simulations

relevant and appropriate materials, tools, equipment and personal protective equipment (PPE) currently used in industry

resources that reflect current industry practices in relation to designing and developing advanced digital systems

applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals.
