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. Learn more about the full course here: techexplorations.com/so/introduction-to-electronics-filters
In this video, we explore the behavior of the RC high-pass filter. You will learn how this circuit blocks low-frequency signals and allows high-frequency signals to pass. We explain how the capacitor and resistor interact to shape the signal’s frequency response, introduce the filter’s transfer function, and show how to calculate the cutoff frequency using the formula fc = 1 / (2πRC). A Python simulation is used to generate a frequency response plot, helping you visualise how the filter attenuates low frequencies while passing higher ones with minimal loss.
