Description
This unit describes the performance outcomes, skills and knowledge required to analyse, apply and simulate the operation of digital signal processing (DSP) to signals in a telecommunications system.Digital signal processing is essential in digital communications systems including signal conditioning and processing functions such as modulation and multiplexing.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the ability to:
apply DSP criteria to a telecommunications system
evaluate LTI system properties
analyse DSP, time and frequency forms of signals by applying signal processing.
Context of and specific resources for assessment
Assessment must ensure:
a telecommunications operations site
digital communication systems, simulation software and telecommunications test equipment currently used in industry.
Method of assessment
A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:
oral or written questioning to assess required knowledge
direct observation of the candidate carrying out analysis and fault solution development within a digital communication system.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
ICTTEN8197A Produce engineering solutions using numerical computations and simulation.
Aboriginal people and other people from a non-English speaking background may have second language issues.
Access must be provided to appropriate learning and assessment support when required.
Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.
In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.
Where applicable, physical resources should include equipment modified for people with special needs.
