A Simple 2nd Order Low-Pass Filter
Low-pass filtering is key for noise reduction, sensor averaging, and controller stabilization. This article introduces a second-order low-pass filter, adjustable via complex pole placement in the Z-plane for optimal resonance and Q factor.
Understanding the Fourier Series - a statistical point of view
One of the most important factors for understanding the phenomena
