Active Filters

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

  • Notch Filter
