Understanding Digital Signal Processing: Key Concepts and Advantages

This overview of Digital Signal Processing (DSP) introduces fundamental concepts of signals, both useful and unwanted. It defines a signal as a carrier of information and explains the basics of signal processing, emphasizing the extraction of useful information from mixed data. The document contrasts analog signals, which vary continuously, with digital signals, which take on discrete values represented as binary numbers. Additionally, it highlights the advantages of DSP over analog signal processing, including cost-effectiveness, flexibility, and efficiency, as well as the benefits of using tools like MATLAB for visualization and analysis.
