In this video, we'll take
In this video, we'll take a look at feedforward filters, a simple filter topology that let's us get into the concept of finite impulse response. We'll subject a simple 1st order feedforward filter to a few control signal and analytically look at the response of the filter and plot its 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.
