ENGN2218 Electrical Systems & Design builds directly on ENGN1218 Introduction to Electrical Systems by developing the students' understanding of the principles and operation of advanced electronic circuits and devices (bipolar junction transistor, operational amplifier, filters, digital logic gates, ADC and DAC, 555 Timer and Instrumentation amplifiers). It also emphasizes the importance of modelling the behaviour of complex electronic circuits and devices using systematic mathematical techniques. Specific topics include:
- Steady State RLC circuit analysis: complex numbers, phasors, impedances, complex power.
- Introduction to Operational Filter Circuits: Transfer functions, Bode Plots, First order active filters (low-pass and high pass).
- Bipolar Junction Transistors: Basic BJT concepts and circuit models, BJT Amplifiers (bias circuits, small-signal and large-signal equivalent circuits), BJT Common Emitter and Common Collector amplifiers, Cascaded BJT amplifiers.
- Introduction to Digital Electronics: Number systems, Boolean algebra, Logic gates, Combinational logic circuits, Karnaugh maps, Combinational logic circuit design.
PSPICE is used extensively in the analysis and design.
Upon successful completion, students will have the knowledge and skills to:
Upon successful completion of this course, students should be able to:
- Apply circuit analysis techniques (e.g. Kirchhoff's laws, Thevenin equivalent circuits, Phasors and complex impedances, Transfer functions) to solve electronic circuits.
- Explain transistor operating modes & analyse operation of basic transistor amplifier circuits.
- Identify first order filter circuits and draw Bode Plots to determine the frequency response.
- Explain analogue to digital and digital to analogue conversion techniques and design combinational logic circuits using Karnaugh Maps.
- Analyse & design electronic circuits for specific applications using op-amps & 555 Timer.
- Explain in simple terms the working of electronic circuits.
- Select appropriate mathematical techniques to analyze and design electronic circuits.
- Utilise a systems approach to identify key design parameters and justify choice of particular electronic components.
- Build circuits and take measurements using electrical measurement devices such as oscilloscope, function generator, digital multimeter, power supply. Compare the measurements with the behavior predicted by mathematic models and explain the discrepancies.
- Model and optimise the performance of analogue and digital electronic circuits using simulation packages such as PSPICE and DigitalWorks.
- Read data sheets and circuit diagrams and recognize building blocks such as op-amp circuits, logic gates, amplifiers, filters and timers
- Calculate results using scientific calculator (complex mode, base-n mode, engineering mode) in a knowledgeable and confident manner
