Filters as the name suggests, they filter the frequency components. That means, they allow certain frequency components and / or reject some other frequency components. In this chapter, let us discuss about the  passive filters . Those are the electric circuits or networks having passive elements like resistor, inductor and capacitor. Types of Filters Filters are mainly classified into  four types  based on the band of frequencies that are allowing and / or the band of frequencies that are rejecting. Following are the types of filters. Low Pass Filter High Pass Filter Band Pass Filter Band Stop Filter Low Pass Filter Low pass filter as the name suggests, it allows (passes) only  low frequency components. That means, it rejects (blocks) all other high frequency components. The s-domain  circuit diagram  (network) of Low Pass Filter is shown in the following figure. It consists of two passive elements resistor and capacitor, which are ...
