Median Filter for Spike Noise Removal using Python
• Introduction to the Digital Signal Process...
Learn how to use a median filter in Python to remove spiky noise from signals effectively. This tutorial demonstrates how the median filter can recover clean signals from high-amplitude spikes.
In this video, we analyze a noisy signal containing spikes of varying magnitudes and apply a median filter with a set threshold to remove spikes above a chosen amplitude. You’ll learn how to select an appropriate threshold and observe the filtered signal compared to the original noisy signal. This practical example shows why the median filter is a robust tool for non-linear signal denoising.
