IST-SElec-Labs\r\n\r\nThis repository contains lab materials for the IST-SElec (Electronic Systems) course.\r\n\r\n# Content\r\n\r\n## [Lab 1: Amplifiers with Feedback](selec_lab1_gr_64.pdf)\r\n\r\nThis project focuses on studying the consequences of negative feedback in amplifiers, exploring configurations with and without feedback to illuminate the impacts on system behavior.\r\n\r\n#### Learning Objectives\r\n- Understand the role of feedback in electronic systems and its implications on system performance.\r\n- Analyze amplifier configurations to observe the effects of feedback mechanisms.\r\n- Use LTspice® for simulation and MATLAB® for data analysis.\r\n\r\n#### Technologies\r\n- LTspice® for circuit simulation.\r\n- MATLAB® for data processing and simulation analysis.\r\n\r\n#### Topics Covered\r\n- Dessensitization of gain due to feedback.\r\n- Reduction of non-linear distortion and noise.\r\n- Control over input and output resistances.\r\n- Bandwidth enhancement of amplifiers.\r\n\r\n## [Lab 2: Proximity Detector Project](selec_lab2_gr_64.pdf)\r\n\r\nAnalyze a proximity detection system based on the principles similar to the Park-Aid circuit, which aids in vehicle parking by detecting nearby obstacles using sensors.\r\n\r\n#### Learning Objectives\r\n- Dissect and study the individual components of the proximity detection circuit, including IR emitter and receiver, band-pass filter, rectifier with filtering, and proximity indicator.\r\n- Evaluate the circuit's performance and functionality as a whole.\r\n\r\n#### Technologies\r\n- LTspice® for circuit simulation.\r\n- MATLAB® for data processing and simulation analysis.\r\n\r\n#### Topics Covered\r\n- Oscillators and their applications in generating periodic signals.\r\n- Analog filters, including active and passive filters for signal processing.\r\n  \r\n## [Lab 3: Embedded Systems Project: μOscilloscope](selec_lab3_gr_64.pdf)\r\n\r\nThe μOscilloscope project aims to design a small oscilloscope as an embedded system for IoT solutions development. The project encompasses understanding the hardware circuit, implementing oscilloscope software, debugging, optimizing, and calibrating the system.\r\n\r\n#### Learning Objectives\r\n- Master the underlying hardware circuitry for the project.\r\n- Develop and implement the μOscilloscope software.\r\n- Perform debugging and software optimization.\r\n- Carry out calibration of the μOscilloscope.\r\n\r\n#### Technologies\r\n- Software implementation compatible with Python 3 and MicroPython®, optimized for microcontrollers.\r\n- MATLAB® for data processing and simulation analysis.\r\n\r\n\r\n#### Topics Covered\r\n- Implementation and calibration of oscilloscope software.\r\n- Signal processing algorithms and concepts.\r\n\r\n## Diagrams and Design Tools\r\n\r\nAll diagrams in this repository were created using [draw.io](https://www.diagrams.net/), with the use of the ECE library provided by [NicklasVraa/Draw-io-ECE](https://github.com/NicklasVraa/Draw-io-ECE). This tool and library facilitated the detailed depiction of electronic components and systems while offering a user-friendly and time-efficient design experience.\r\n\r\n## License\r\n\r\nThis work is licensed under a [Creative Commons Attribution Non Commercial Share Alike 4.0 International][cc-by-nc-sa].\r\n\r\n[cc-by-nc-sa]: https://creativecommons.org/licenses/by-nc-sa/4.0/legalcode\r\n\r\n## Authors\r\n\r\n- [João Gonçalves - sqrt(-1)](https://github.com/eusouojoao)\r\n- [Teresa Nogueira - 13A!](https://github.com/FrolickingAsteroid)\r\n\r\n## Contributing\r\n\r\nIf you have suggestions or find any issues, please open an issue or submit a pull request.\r\n\r\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkons-5%2Fist-selec-labs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkons-5%2Fist-selec-labs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkons-5%2Fist-selec-labs/lists"}
