Introduction to Electronics: Filters - Compare a filtered and unfiltered signal

This video is part of the "Introduction to Electronics: Filters" course, created to help beginners understand the principles and applications of electronic filters through hands-on projects. You will explore essential topics like RC and RL filters, cutoff frequency, phase shift, Bode plots, and how filters are used in audio, sensors, and power supplies.

In this video, we demonstrate how a low-pass filter can clean up a noisy signal. By comparing an unfiltered signal with a filtered version using a simple RC circuit and Python simulation, you will see how high-frequency noise is removed to reveal the true low-frequency content. This example builds your intuitive understanding of filtering before we dive deeper into the technical and mathematical details later in the course. Filtering like this is essential for improving the quality of sensor readings and signal processing in real-world electronics.
