ELEC70055 Instrumentation

Lecturer(s): Dr Christos Papavassiliou


This module will give you an overview of electrical measurement theory and practice, especially at high frequencies. A main objective is to provide you with an understanding of measurement capabilities and limitations.

Learning Outcomes

Upon successful completion of this module, you will be able to: 1. argue the operation principles and limitations of various measurement sensors/transducers for mechanical and electromagnetic stimuli. 2. defend the use of recently invented sensors (SQUID, GMR, QHE, etc) in applications with severe performance requirements. 3. design interface circuits to optimise transducer performance. 4. develop embedded code to implement data acquisition (including subsampling and irregular sampling) and signal conditioning 5. assemble a PCB level prototype of a specified measurement instrument


Definitions and examples of measurements and their limitations: Resolution, accuracy, sensitivity. Noise in electronic systems. Analogue, Digital and Sampling Oscilloscopes;
DC and AC bridges. Amplifiers. Sampling and Analogue to Digital conversion;
Oversampling. Oscillators and synthesisers. Phase noise. Frequency measurements;
Coherent measurements and interferometry. Correlation techniques. Network and spectrum analysis at radio frequencies. Time Domain Reflectometry.
