In the RC low-pass filter, the path to the ground goes through a capacitor, which means impedance will decrease with increasing frequency. Therefore, in this circuit, the ratio of the Vi down to the Vo will depend on the values of R and C and the signal’s frequency. With high frequencies, impedance is low, and energy is sent to the ground as Vi is divided. Low frequencies see a higher impedance, sending energy to the output.

Filters that contain one or more capacitor elements with paper, plastic film, or ceramic dielectric combined with one or more inductive elements in the form of ferrites or chokes are called LC filters. Ceramic capacitors used are of feed-through type, where one terminal consists of the casing soldered or screwed to the chassis. Or there are SMD variants.

The term “quality facto”,r or Q factor, is used as a shorthand figure of merit (FOM) for RF filters. In short, the Q factor is expressed as the ratio of stored versus lost energy per oscillation cycle. More specifically, the Q factor generally describes specifications such as the steepness of skirts or the selectivity and how low the insertion loss is. Overall losses through a resonator increase as the Q factor drops and will increase more rapidly with frequency for lower values of resonator Q.
