An Introduction to Signal Processing

This lecture introduces the fundamentals of signal processing, covering analog and digital signals, time/frequency domains, transforms, filters, converters, and embedded systems. It explores the core components shared by systems in environmental engineering, such as sensing, processing, mobility, communication, and visualization. The course aims to equip students with the skills to become proficient users of key instruments in environmental engineering, preparing them for advanced master courses. Practical exercises, labs, and homework assignments provide hands-on experience with tools like Matlab, C programming, and robotic simulators. The lecture emphasizes the importance of understanding signal classification, analog-digital conversion, and the applications of ADCs and DACs.
