What an assessment for ICTTEN826 must cover

31 assessable components: 4 elements (12 performance criteria), 6 performance evidence and 8 knowledge evidence requirements, plus 5 foundation skills. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.

Elements & performance criteria

1 Apply DSP design criteria to network system

  • 1.1Review DSP criteria applied to signal processing
  • 1.2Perform frequency domain analysis on network signals
  • 1.3Apply digital processing techniques to DSP baseband communications signals used in digital systems
  • 1.4Generate output of a comb filter in digital filtering application using convolution theorem and autocorrelation

2 Determine linear time invariant (LTI) system properties

  • 2.1Simulate network entities using simulation software functions
  • 2.2Perform calculations to find numerical approximations of the continuous-time convolution process
  • 2.3Simulate echo cancellation by applying simulation software using adaptive DSP algorithms and an inverse filtering method

3 Analyse digital network signals processing

  • 3.1Analyse the result of digitally passing a signal through a first- order recursive discrete-time filter
  • 3.2Determine frequency response of a simple continuous-time system using Fourier transform
  • 3.3Analyse amplitude modulated signals using Fourier transform

4 Analyse time and frequency forms of signals

  • 4.1Program a simulated software application and represent a comb filter with a signal applied from the required network system
  • 4.2Produce a report analysing simulated output results and relevance of a DSP filter to a network system

Performance evidence

  • evaluate and apply at least two digital signal processes to communication systems.
  • apply digital signal processing (DSP) criteria to a network system
  • evaluate linear time invariant (LTI) system properties
  • analyse digital and amplitude modulated signals using DSP methods and principles
  • demonstrate an awareness of radio frequency issues required to DSP processes
  • report on finding of analysis and use of DSP in a network system.

Knowledge evidence

  • required legislation, codes, company work practices, regulations and standards, workplace health and safety (WHS) requirements for scoped work
  • digital communications systems
  • Fourier transforms
  • LTI
  • various modulation methods, amplitude (AM), frequency (FM), phase (PM) and digital formats
  • organisational policy and procedures for digital signal processing
  • common non-compliance issues and responses
  • workplace technical documentation and related reports.

Foundation skills

  • Numeracy: Performs a range of complex, algorithmic calculations and analyses. Analyses and synthesises highly embedded mathematical information in a broad range of tasks and texts
  • Reading: Researches, evaluates and interprets complex technical documentation
  • Writing: Prepares workplace documentation including reports that incorporate technical language to communicate complex information clearly and effectively
  • Planning and organising: Uses different processes to identify key information and issues, evaluate alternative strategies, anticipate consequences and consider implementation issues and contingencies. Takes responsibility for high-impact decisions in complex situations involving many variables and constraints
  • Technology: Uses advanced features and functions of digital tools to complete work tasks

Questions about assessing ICTTEN826

What does an assessment tool for ICTTEN826 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for ICTTEN826 needs to address all 31 unit components: 4 elements with 12 performance criteria, 6 performance evidence requirements, 8 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for ICTTEN826?

Auditori pulls the current release of ICTTEN826 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for ICTTEN826 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing ICTTEN826 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of ICTTEN826, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
