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

The simulation shows implementation of LC π and T filters designed for a 1 kHz signal. Both filters use 100 nF capacitors and 10 mH inductors, giving a cutoff frequency around 1.6 kHz. The π filter uses a capacitor–inductor–capacitor (C–L–C) structure, while the T filter uses an inductor–capacitor–inductor (L–C–L) layout. The simulation input is a 2 kHz sine wave, slightly above the cutoff, allowing clear observation of attenuation. The output waveforms confirm proper low-pass filter behavior, w
