Electronics: sensing, logic and actuation

Electronics underpins almost every facet of the modern world, controlling the smallest of surgical instruments to the largest of passenger planes, with imminent new developments such as autonomous cars and collaborative robots. You’ll gain industrially relevant skills in the core aspects of electronics: sensing gives detailed awareness of the world, logic makes smart decisions and actuation produces tangible outputs. The theory you’ll learn is applicable industry wide, enhanced by regular sessions in our remote laboratory where you’ll personally have full real-time control over state-of-the-art electronics equipment, from your own computer.

What you will study

This module will provide you with an introduction to the broad spectrum of activities that comprise electronic engineering, and the analytical methods needed to support it. It is designed to give continuity into Electronics: signal processing, control and communications (T312) – planned for October 2019. The combined modules will have a strong emphasis on the development of the practical knowledge and skills required by industry.

It’s presented in five blocks. The first block introduces the module and shows how sensors, logic and actuation are combined to make working systems. The context of the overall module is the sensing–logic–actuation cycle, in which electronic systems (i) collect information about their environment through sensors responding to light, sound and other physical phenomena, (ii) use logic and signal processing to reason about the sensor data in the context of what they already know, in order to plan and decide what to do next, and (iii) control their motors and actuators such as wheels, legs, arms, and grippers to move and operate successfully within their environment. The theory will be illustrated by many electronic systems, from the devices that are everywhere in our homes and everyday lives to state-of-the-art systems across a range of application areas.

Block 1: introduction  This block introduces and motivates the module, explaining the roles of sensing, logic and actuation in electronics engineering. Building on the basic theory of electricity, you’ll learn about common electronic devices and how they work together to make circuits with standard functionality. You’ll learn how to read and draw schematic diagrams for electronic systems. This is supported by the industry-standard Multisim Live circuit design and simulation software. You’ll be introduced to the OpenEngineering Laboratory, and conduct an experiment on a driven pendulum that produces sine wave signals similar to those you’ll see in electrical and electronic systems.

Block 2: Sensing – You’ll learn about sensors, signals and signal processing. You’ll learn how a variety of sensors work, including light-dependent resistors, photodiodes, thermistors, pressure sensors, and ranging devices, and how to design robust sensor circuits using operational amplifiers (op-amps). The theory of Fourier analysis is developed and used as the basis of signal processing, including sampling and filtering. You’ll use your computer to investigate various aspects of signal processing and filtering out noise.  Multisim Live and OpenEngineering Laboratory experiments will give you experience of sensor circuit design and signal processing using industry-standard interfaces controlling real devices.  The OpenEngineering Laboratory experiments include photodiodes and strain gauges.

Block 3: Logic – This block covers the basics of Boolean logic and the use of binary numbers and sequential logic in computing devices and controlling systems. You’ll learn about microcontrollers and microprocessors, including how they can be programmed to read sensors and control actuators. In your OpenEngineering Laboratory experiments, you’ll use a specially-designed digital logic tutor board, with real digital logic gates, that can be rewired instantly from your computer.

Block 4: Actuation – This block covers actuators and the circuits that drive them. You’ll learn about transistors and semiconductors; electromagnetics; linear actuators; DC motors and stepper motors; cooling in electronics; and control. You’ll use the OpenEngineering Laboratory and Multisim Live extensively. The OpenEngineering Laboratory exercises will involve controlling a variety of motors and measuring their properties.

Block 5: Integration – This block uses the case study of a quadcopter drone to illustrate the process of designing electronic and mechanical systems. You'll learn that the integration process iterates between the design of the whole system and the design of its interacting subsystem. The OpenEngineering Laboratory exercise experiments with ranging devices.

Tuition will take place across a range of media; there will be online and face-to-face tutorials that you are strongly encouraged to attend.  Where your tutorials are held will depend on the distribution of students taking the module.

Your tutor will also support you in your online activities, including using Multisim Live and the OpenEngineering Laboratory.

Assessment

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

You must use the online eTMA system to submit your tutor-marked assignments (TMAs).

Block quizzes help you prepare for the three TMAs and EMA.  The quizzes are formative which means that they don’t count towards the final mark. Their purpose is to enable you to test for yourself how well you have understood what is being taught, and you can try the questions any number of times without penalty.

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.
