Components and modules explained
Components are the blocks of study that make up your course. A component may have a set module which you must study, or a number of modules from which you can choose.
Each component has a status and carries a certain number of credits towards your qualification.
What this means
You must take the set module for this component and you must pass. No failure can be permitted.
Core with Options
You can choose which module to study from the available options for this component but you must pass. No failure can be permitted.
You must take the set module for this component. There may be limited opportunities to continue on the course/be eligible for the qualification if you fail.

You can choose which module to study from the available options for this component. There may be limited opportunities to continue on the course/be eligible for the qualification if you fail.
You can choose which module to study from the available options for this component. There may be limited opportunities to continue on the course/be eligible for the qualification if you fail.
The modules that are available for you to choose for each component will depend on several factors, including which modules you have chosen for other components, which modules you have completed in previous years of your course, and which term the module is taught in.
Modules are the individual units of study for your course. Each module has its own set of learning outcomes and assessment criteria and also carries a certain number of credits.
In most cases you will study one module per component, but in some cases you may need to study more than one module. For example, a 30-credit component may comprise of either one 30-credit module, or two 15-credit modules, depending on the options available.
Modules may be taught at different times of the year and by a different department or school to the one your course is primarily based in. You can find this information from the module code. For example, the module code HR100-4-FY means:
The department or school the module will be taught by.
In this example, the module would be taught by the Department of History.

Computers, embedded systems, and digital systems in general have become an essential part of most people's lives, whether directly or indirectly. The aim of this module is to introduce the software and hardware underpinnings of such systems at an introductory yet challenging level suitable for future computer scientists and engineers. Topics covered in the module include both top-view as well as bottom-view approaches to understanding digital computers. They range from the more theoretical (e.g., state machines, logic circuits, and von Neumann's architecture) to the more practical (e.g., how transistors produce binary signals, operating system functions, memory management, and common hardware devices). The module also includes problem solving classes in which a guided discussion of weekly exercises is aimed at giving the student an opportunity to consolidate his/her understanding of the topics involved. Upon completion of this module, students should have a good conceptual and practical understanding of the nature and architecture of digital computer systems and their components.
This module develops the fundamental concepts introduced in the Digital Systems Architecture. We examine how data are represented within digital systems, including floating point, 'text' and 'data' files, and how the conversions between internal and human-readable forms are performed. The design and applications of higher-level logic elements such as counters, registers and multiplexers are discussed, as well as the more general concept of the finite state machine and its design. Transmission of digital data between systems is introduced by examination of the RS232 protocol. Further, fundamental decisions on how such sources should be represented in digital format include sample rates and quantization accuracy are discussed. In the case of audio and video especially, the possibilities for signal processing and data compression are investigated
This module is one of two concerned with scientific and engineering foundations on which electronics is based. All electronics components are based on physical principles that relate voltage, current flow and the storage or loss of energy. All the theory we need to learn about how circuits behave is based on the fact that electric charge cannot be created or destroyed, and that the energy of each electron just depends on where it is, and how fast it is moving. How charges move in materials depends on their crystal structures. From basic ideas, the main principles of electronics are built up so that they can be used in the wider study of electronics to solve problems.
This module comprises the second half of our 1st year series on fundamentals of electronics. The module focuses on reactive circuits (i.e., circuits with capacitors and/or inductors), basic semiconductors (i.e., diodes and bipolar junction transistors), electromotive devices, and operational amplifiers. The overview of these devices includes more theoretical concepts (such as Faraday's and Lenz’s laws) as well as more practical topics such as their transient and steady state responses to step and sinusoidal inputs, using phasors for circuit analysis, applications in analogue filters, amplification with feedback, power supply units, and DC motors and generators. The module includes weekly problem solving classes in which calculation exercises are discussed and four weekly lab sessions in which more theoretical concepts are applied to implementation and testing of a DC power supply unit.
This course covers the principles of project management, team working, communication, legal issues, finance, and company organisation. Working in small teams, students will go through the full project life-cycle of design, development and implementation, for a bespoke software requirement. In this course, students gain vital experience to enable them to enter the computer science/Electrical engineering workforce, with a degree backed by the British Computer Society, and by the Institute of Engineering and Technology.

This module aims to develop an in-depth understanding of analogue systems and circuit techniques from the perspective of the design process. The module incorporates two major themes: The first is the circuit orientated theme aiming to engender both an intuitive understanding of simple circuit design and functionality.The second theme focuses on the more formal analysis and computer simulation techniques using equivalent circuit transistor models where key skills in numeracy and circuit simulation are developed and then used in the design, simulation and construction of oscillator circuits. The module is supported by laboratory-based assignments that investigate small signal amplifiers, and voltage-controlled oscillator design and applications.
Digital systems are an important part of most electronic devices and systems. In this module students learn to design a small system using an industry-standard prototyping board based around a Xilinx FPGA. The module is laboratory based using Xilinx Computer-Aided Design (CAD) software and it builds on knowledge of digital circuits that students learn in CE161. Students learn how to design, and more importantly, how to debug and test a design, using laboratory test equipment, to convert an idea into working hardware.
This module provides you with a basic understanding of the analysis of linear systems and introduces you to filter design techniques for analogue signal processing.

Discrete signals and systems are studied, with an emphasis on the Fourier and Z-transforms that are necessary for the analysis of discrete signals and design of digital filters.
This module aims to provide you with a detailed description of the data link layer of telecommunications systems and its interface with the physical layer of these systems. It starts by using the OSI model to place these layers in the context of the entire telecommunication system. It then describes the principal methods for the quantitative description of link signals, which then enables the fundamental link layer transmission media to be described as well as of baseband transmission. A discussion of link layer flow control and error correction naturally leads to description of link layer protocols. Finally, the transmission of digital signals over analogue links and analogue signals over digital lines are discussed.
