PassiveFilter. - Here is Circuit Schematic Band reject filter includes compensation for Band Pass Filter. Some band-reject LC filters employ a reactance to decouple individual resonators. One such filter uses relatively small shunt inductors to decouple series resonators, known as a top-L coupling. This type of coupling readily achieves narrow filter bandwidths while....
