Description
Employability Skills
Learning Outcomes and Application This unit describes the skills and knowledge required to analyse, apply and simulate operation of digital signal processing (DSP) to signals in a telecommunications system.It applies to individuals with excellent information technology (IT) and design skills working as field officers. They develop solutions in modern applications, such as internet protocol TV (IPTV), digital TV, fast broadband and internet applications.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications networks engineering field of work and include access to:

a telecommunications operations site

digital communication systems

simulation software

telecommunications test equipment currently used in industry.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
