Basic electronics from the courses of Electrotechnics or Electromagnetic Fields and Circuits I

The course is meant to provide an overview on electronics for application to industrial measurements. The main topics are signal amplification, filtering, and generation, A-to-D and D-to-A conversion, stochastic noise and disturbances. Operation of the most important instruments for circuit characterization is also discussed. The course includes practical activities to be carried out in the electronic laboratory.

1) Introduction. Electronic chain for signal processing and acquisition: amplification, filtering, sampling, quantization, analog to digital conversion.
2) Circuits in the time domain, delta and step response. Circuits in the frequency domain, Fourier analysis and Laplace transform, impedance, frequency response and transfer function, Bode diagrams.
3) Ideal operational amplifier. Non-idealities in op amps. Negative feedback. Inverting and non-inverting amplifiers. Voltage buffer. Ideal integrator and differentiator. Difference amplifiers. Instrumentation amplifiers.
4) Signal filtering. Passive and active filters.
5) The diode. Electronic circuits with diodes.
6) The bipolar junction transistor. Amplification schemes based on bipolar transistors.
7) The MOSFET transistor. Digital circuits with MOSFET transistors. Combinational and sequential circuits. Analysis and synthesis of logic circuits.
8) Circuit design and fabrication. Printed circuit technology. Integrated circuit technology.
9) Review of analog-to-digital and digital-to-analog conversion. Sampling theorem and signal sampling, spectral representation of sampled signals, aliasing, quantization. Simple schemes for A to D and D to A conversion.
10) Disturbances and stochastic noise in amplifiers. Power supply rejection ratio (PSRR). Random noise treatment in electronic circuits.
11) Instrumentation for electronic circuit characterization: oscilloscopes, multimeters, signal generators.
12) Experimental activity in the electronic laboratory. Design of circuits for signal conditioning. Signal acquisition and processing in the LabView environment.

1) Written exam.
Closed-book, closed-notes, 2 hour written exam consisting of 4 to 6 sections assessing the student’s knowledge and understanding of the course topics and problem solving capabilities. Threshold to pass the exam is 18/30, maximum mark is 30/30 cum laude. The final mark for the written exam will result from the weighted average of the marks obtained in each section of the written exam.
2) Oral exam.
Typical duration is 1/2 hour, including the revision of the written exam and 1-2 questions. The exam will assess the student’s knowledge and understanding of the course topics, problem solving capabilities and technical communication skills. Threshold to pass the exam is 18/30, maximum mark is 30/30 cum laude. The final mark for the oral exam will result from the weighted average of the marks obtained for each question of the oral exam.
The final mark for the overall exam will result from the weighted average of the written exam (70%) and the oral exam (30%) marks. Threshold to pass the exam is 18/30, maximum mark is 30/30 cum laude.
