Signals, Systems, and Signal Processing Explained | Definition, Source, Types & DSP Algorithms
Welcome to EC Academy! This lecture is a must-watch foundation for anyone starting in engineering or signal processing. We clearly define signals, systems, and signal processing, and explore how they interrelate. Learn the precise definition of a signal as a dependent variable, see examples of natural signals like ECG and EEG, and understand the role of a system in processing signals. We dive into the concept of Digital Signal Processing (DSP), including the use of algorithms in both software and hardware systems, and touch upon key topics like filtering and spectral analysis.
