Electronics is all around us today: in our homes, the workplace, cars and even on
or in our bodies. It’s hard to believe that it was only in 1947 that the transistor was
developed by American physicists John Bardeen, Walter Brattain, and William
Shockley. The invention of the transistor paved the way for cheaper radios,
calculators and computers.
This unit introduces students to the use of electronics manufacturers’ data to
analyse the performance of circuits and devices, the operational characteristics of
amplifier circuits, the types and effects of feedback on a circuit performance, and
the operation and application of oscillators. They will also be introduced to the
application of testing procedures to electronic devices and circuits, and use the
findings of the tests to evaluate their operation.
Among the topics included in this unit are: power amplifiers, class A, B and AB;
operational amplifiers, inverting, non-inverting, differential, summing, integrator,
differentiator; types such as open, closed, positive and negative feedback;
frequency, stability, frequency drift, distortion, amplitude, wave shapes and testing
On successful completion of this unit students will be able to determine the
operational characteristics of amplifier circuits, investigate the types and effects of
feedback on an amplifier’s performance, examine the operation and application of
oscillators and apply testing procedures to electronic devices and circuits.

The use of Computer Aided Design (CAD) and simulation in the electronic and
electrical engineering industry is ever growing. Commercial software packages
enable an engineer to design, simulate, model and predict the outcome of a design
before a product has been made. This enables time and cost savings in the
development of a product whilst enabling the engineer to further develop their
The aim of this unit is to introduce students to the availability and use of
commercial software packages within electronics engineering, including design,
simulation, simple microprocessor programming and evaluation of the tools
On successful completion of this unit students will be able to research a range of
software tools or applications to support engineering functions related to
electronics, consider how a software package can be used to simulate the
behaviour of an electronic circuits function, explain how to programme a
microprocessor-based device to achieve a specified outcome/task, evaluate a
specific electronics software tool/application, describe the types of commercial
software available, compare the differences between a software simulation and a
real-world circuit, and write simple commands to a microcontroller.

The speed and efficiency of many industrial processes is due, largely, to the control
systems selected for the application and the engineer’s ability to apply the most
appropriate technology for their operation.
This unit presents a structured approach to the development of advanced electronic
solutions in a range of industrial situations. An essential requirement here is the
engineer’s ability to utilise the most appropriate technology for each application, to
ensure the most efficient monitoring and control of variables such as pressure,
temperature and speed.
Among the topics included in this unit are techniques and applications of electrical
and electronic engineering, as they apply to various branches of industry, such as
component handling, controlling the speed or torque of a motor or responding to
change of circumstances in a process.
On successful completion of this unit students will be able to describe system
elements and consider their overall characteristics. This provides opportunity for
analytically assessing the accuracy and repeatability of electronic instruments.

This unit presents a wide-ranging introduction to the field of existing and renewable
energy systems. There are many alternative sources of energy (some ‘green’)
which can be converted to an electrical form, providing energy for transport,
heat/cooling and lighting, as well as energy for various industrial processes and
Power electronic converters are an essential component of renewable and
distributed energy sources, including wind turbines, photovoltaics, marine energy
systems and energy storage systems. It is necessary to gain a clear understanding
of, and be able to examine, the technical implications of providing sustainable
electrical energy to meet the energy demand of the future.
The unit will also explore the potential impacts of climate change and why more,
and different forms of, sustainable energy sources are required together with the
need for energy efficiency measures.
By the end of this unit students will be able to examine the technological concepts
behind providing a sustainable electrical energy supply for the future. They will also
be able to describe how the fundamental technical and economic processes and
drivers at play in the electrical power industry affect the selection and use of
