Evidence of ability to:
apply digital signal processing (DSP) criteria to a telecommunications 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 relevant to DSP processes
report on finding of analysis and use of DSP in a telecommunications system.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
To complete the unit requirements safely and effectively, the individual must:
summarise digital communications systems
explain Fourier transforms
explain linear time invariant (LTI)
explain various modulation methods, amplitude (AM), frequency (FM), phase (PM) and digital formats
explain organisational policy and procedures for digital signal processing
outline common non-compliance issues and responses.
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.
