2. Digital Filter Basics & Characteristics 📊

We'll look at what a filter is, and narrow our focus on digital filters. We'll look at ways of analyzing the behavior of a filter by studying the characteristics of the filter, it's frequency and phase response.

In this series on Digital Filter Basics, we'll take a slow and cemented dive into the fascinating world of digital filter theory. Many resources present this topic with dense and exhausting mathematics. Although a fair understanding of complex mathematics is required to fully comprehend the science of filter design, understanding the basics of filters and how they fundamentally work is better left to analysis and visualizations, which I try to do in this series. We'll learn about feedforward and feedback filter topologies, impulse and impulse responses and and wide variety of other topics.
