Passive RC high pass filters

This video builds upon the basics I covered with my low pass filter tutorial, so make sure you have seen that video first. This video shows you how high pass filters affect sine waves and square waves of different frequencies, and compares the bode plots of high and low pass filters. By the end of the video you’ll know how to remove the DC component of signals (very helpful in amplifier designs!) and you’ll be able to design filters to remove any low frequencies you want.
