Filter capacitors work based on the principle of capacitive reactance. Capacitive reactance is a capacitor''s opposition to the flow of alternating current (AC). In an AC circuit, the voltage and current continuously change direction, and the capacitor charges and discharges in response to these changes. As the AC voltage increases, the capacitor charges up to the peak

Basic Introduction to Filters

filter is usually equal to the total number of capacitors and inductors in the circuit. (A capacitor built by combining two or more individual capacitors is still one capacitor.) Higher-order filters will obviously be more expensive to build, since they use more components, and they will also be more complicat-ed to design. However, higher-order filters can more effec-tively discriminate
