active high pass filter
What does an active high pass filter do?
Active high pass filters pass signals from high frequencies and reject signals from low frequencies.
There are two basic types of products: switched capacitor and continuous.
Both are available with first to eighth order filtering.
Switched capacitor active high pass filters are clocked devices.What is high pass filter used for?
A high-pass filter is an EQ curve that is used to remove low-frequency sounds from an audio signal.
It is called a high-pass filter because it allows high-frequency signals to pass through, while attenuating (reducing the amplitude of) lower-frequency signals.Filters can be active or passive, and the four main types of filters are low-pass, high-pass, band-pass, and notch/band-reject (though there are also all-pass filters).
I hope you've learned a bit about how to describe filters and what they can accomplish.

How does an active filter work?
An active filter is a type of analog circuit implementing an electronic filter using active components, typically an amplifier.
Amplifiers included in a filter design can be used to improve the cost, performance and predictability of a filter.
