Dive into the world of digital filter design and implementation in this comprehensive video tutorial. Learn the fundamentals of digital filters, including their basic elements and how they manipulate signals. Explore feed-forward (FIR) and feed-back (IIR) filters, as well as Biquad Second Order Sections (SOS). Gain hands-on experience with hardware setup, DMA explanation, and filter coefficient calculation. Follow along with simulations using Jupyter and Anaconda, and see practical applications in audio filtering. Understand C code implementation for both simulations and microcontrollers. By the end, acquire the knowledge and skills to design and implement your own digital filters.
