ENAP0091: Instrumentation & measurement I Semester 1 Credits: 3 Contact: Level: Level 1 Assessment: EX100 Requisites: Aims & Learning Objectives: To provide an introduction to measurement, instrumentation and signal processing. After taking this unit the student should be able to: i) match an indicating instrument or data recorder to a given signal source and estimate the accuracy of the indicated output; ii) select a suitable transducer type for a particular measurement application iii) describe the shielding and guarding techniques that are necessary to keep extraneous signals in the environment from affecting the signals in a measurement system. Content: Transducers for a range of measurements, such as: displacement, strain, acceleration, force, velocity, torque; operating principles, characteristics, selection based on application requirements. Measurement of voltage, current and resistance. Use of bridge circuits. Matching of instruments to signal sources. Thevenin's therom. Explanation of concepts of accuracy, systematic and random errors, noise, linearity and repeatability of measurements. Signal amplification; amplifier types, signal buffers, instrumntation amplifiers and active filters. Amplifier errors and drift. AC characteristics, band-width, signal-to-noise ratio. Brief description of guarding and shielding techniques. |

ENAP0093: Instrumentation review project Semester 1 Credits: 3 Contact: Level: Level 2 Assessment: RT60 OR40 Requisites: Pre ELEC0078 Aims & Learning Objectives: To develop skills in applying measurement and instrumentation techniques for sports applications via problem based project work. After taking this unit the student should be able to: Carry out detailed systematic analyses of the measurement and instrumentation systems for a range of sports engineering applications. Content: Working in groups the students will prepare a series of reports describing in details the issues relating to measurement and instrumentation in a series of particular sports applications. They will make presentations on their findings and also prepare reports. The outcomes will be focused on the optimal methods that should be used. This will be a literatue based exercise. |
