Application

This unit describes the skills and knowledge required to analyse, apply and simulate operation of digital signal processing (DSP) to signals in a network system.

It applies to individuals with excellent information and communications technology (ICT) 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.
