Components—Part 3: The Performance of LC Filters
A capacitor readily passes high-frequency currents; an inductor (coil) doesn''t. When the two are combined, they form a resonant circuit that oscillates at a specific frequency. LC filters ("L" represents inductor; "C" represents capacitor), which selectively remove high-frequency noise, work under the same principle. Today, multilayer, chip-type LC filters play major …
