RLC Low-pass Filter

own work

Filters can remove low and/or high frequencies from an electronic signal. They can be used to suppress unwanted frequencies such as background noise. This article shows the math and visualizes the poles in the s-place, examines and visualizes the the step and frequency response. «read more»

RC Low-pass Filter
