Signal processing courses can help you learn about Fourier transforms, filtering techniques, and signal modulation. You can build skills in analyzing audio and visual signals, implementing algorithms for noise reduction, and working with time-frequency analysis. Many courses introduce tools like MATLAB and Python libraries, that support simulating signal processing techniques and analyzing real-world data.
