What are the classification of filters? 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).
How are active filters classified?
Active power filters are power electronic devices dedicated to improving the quality of the electrical energy and the efficiency of its use. This chapter presents the different types of active power filters according to their type—shunt, series, and hybrid.
How are filters classified based on their frequency response?
The five main types of frequency filters are the high pass, low-pass, all-pass, band pass, and notch filters. Their characteristics are determined by the type and values of circuit components used as well as their arrangement. The classification is based on the frequency range that a filter allows to passes through.
