First-order RC low-pass filter with a 1kHz cutoff frequency. Passes signals below 1kHz and attenuates higher frequencies at -20dB/decade. The simulation shows input vs output waveforms so you can see attenuation in real time. Sweep the frequency to observe the -3dB point. Essential building block for audio, sensor conditioning, and power supply filtering.
