In this video, electrical engineer Barron Stone designs a passive RC high-pass filter to remove low-frequency energy from a signal while allowing high-frequency energy to pass through. Learn how a capacitor can be used to remove unwanted DC offset from a
- [Instructor] A high-pass filter is a circuit that…attenuates or reduces any low-frequency components…of a signal, while allowing the high-frequency components…of that signal to pass through.…A high-pass RC filter can be built…using the same components as a low-pass RC filter.…The difference between the two types of filters…is that the locations of…the resistor and capacitor are swapped.…In a high-pass RC filter, the capacitor is in series…with the output, and the resistor is in parallel…with the output.…
In this configuration, I like to think of the output node…as a, an exclusive dance club,…and the capacitor is a bouncer that decides which…frequencies get to come into the club.…So when high-frequency signals come up to the bouncer,…he lowers his impedance…and he lets them right on in.…But when low-frequency signals try to get into the club,…that bouncer's going to raise his impedance…and block them.…Now, inside the club, the high-frequency energy…that got past the bouncer needs somewhere to go.…
Some of that energy might continue on…
