This simulation showcases two types of LC filters—the π filter (C-L-C) and the T filter (L-C-L)—commonly used in power supply circuits for smoothing voltage. The top waveform graph displays the signal filtering effect, showing reduced ripple after passing through these filters. The π filter uses two capacitors with an inductor between, ideal for filtering high-frequency noise. The T filter, on the other hand, uses two inductors with a capacitor between, offering better performance for heavy curr
