Electronics: signal processing, control and communications

This module teaches industry-relevant skills in applying analogue and digital electronics to signal processing, control and communications. Signal processing looks at how analogue or digital filters can remove signal noise. Control shows how using feedback and a suitable controller can change the dynamic behaviour of processes (electronic/mechanical or other) to meet a desired criterion. Communication shows how cables and radio waves can communicate data.

What you will study

This module takes the ideas that you know about basic electronic circuits, together with general engineering principles, and looks at three of the main applications of electronics. It comprises three blocks: signal processing, control and communications.

Interactive software and OpenEngineering Laboratory experiments support the course materials in all three blocks. Throughout the module, we use illustrative case studies.

Block 1: Signal processing
The first block introduces you to signal processing. It starts by defining what we mean by noise in a signal, showing how to explain this in the frequency domain. It then shows how we can remove the noise with the use of analogue electronic circuits – called filters. We’ll show you how to design filters to perform specific tasks by using mathematical models. We’ll also give you a refresher on complex numbers. The block ends with a look at digital filters. First, how we can design filters that run on computers and can perform many of the filtering tasks of analogue circuits. Finally, we look at aspects of processing that we can only do with digital signals, such as image processing.

Block 2: Control
This block introduces the idea of control theory. It discusses the basic principle of using feedback, as well as processes’ transient responses. Block 2 extends some of the ideas of mathematical modelling introduced in Block 1, so you can start designing controllers that produce the desired behaviour of a process. You’ll spend some time looking at how to implement controllers electronically in both analogue circuits and as digital algorithms. You’ll then look at some of the ideas of intelligent control, specifically fuzzy logic control and neural networks.

Block 3: Communication
The final block introduces the principles of communication, with emphasis on radio communications. It starts by looking at modulation, and how to encode a message into a radio frequency waveform. It shows the design and implementation of transmission and receiver circuits, and how radio frequency circuits differ from electronic circuits. You’ll consider aspects of both analogue and digital communications and explore the advantages of each. Finally, you’ll look at space communications – the problems that are inherent, together with the solutions.

You will learn

The knowledge and skills developed in this module are applicable in various engineering roles. At the end of it you’ll be able to:

  • describe the application of electronic systems in signal processing, control and communications
  • search and use relevant journal papers via the library website
  • work with signals, including sampling and filtering
  • design controllers to achieve a desired dynamic response
  • design radio frequency circuits for transmitters and receivers
  • work with equipment using the OpenEngineering Laboratory.

Vocational relevance

This module will help you to gain knowledge and skills that are essential for the practising engineer. It can help you to:

  • be aware of the role played by electronics in general engineering
  • apply standard electronic theory to practical engineering problems
  • use industry-standard software to solve problems
  • use industry-standard hardware in electronics engineering in the OpenEngineering Laboratory
  • reflect on and improve your personal and professional development as an engineer.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

Assessment

The assessment details for this module can be found in the facts box.

Both the TMAs and EMA assess the module material as well as practical (Open Engineering Lab) and simulation activities.

Block quizzes help you prepare for the assessments. The quizzes don’t count towards the final mark. Their purpose is to support your learning and determine for yourself how well you’ve understood the teaching.

Future availability

Ways to pay for this module

Open University Student Budget Account

The Open University Student Budget Accounts Ltd (OUSBA) offers a convenient 'pay as you go' option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that The Open University works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

You pay the OU through OUSBA in one of the following ways:

  • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
  • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

Joint loan applications

If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
