MATLAB: Remove Noise Using a Low-Pass Filter (Step by Step)
In this video, we demonstrate how to remove noise from a signal using a low-pass filter in MATLAB, step by step.
You will learn how to:
Start from a noisy signal
Design a low-pass filter in MATLAB
Apply the filter to reduce noise
Visualize the filtered signal
Compare noisy and filtered signals clearly
This tutorial focuses on practical signal processing through visualization, without heavy mathematics.
It is designed for students and beginners who want to understand how filtering improves signal quality in real systems.
