An active filter is a type of analog circuit that implements an electronic filter to a signal using active components such as an amplifier. When an amplifier is included in a filter design or application, it can improve the predictability and performance of the filter.
Types of Active Filters
Brand Pass Filters
Brand Reject Filter
High Pass Filter
Low pass Filter
Quad Filters and Universal Filters are devices that can be programmed to perform one of the other types of active filters
