Schematic

Demonstrates a first-order RC low-pass filter.

Circuit Summary

A series resistor feeds a capacitor to ground; the output is across the capacitor.

Expected Behavior

  • AC sweep shows a -3 dB cutoff at 1/(2πRC).
  • Transient response smooths fast edges.

How To Run

  1. Open RC-Lowpass.kicad_sch in KiCad.
  2. Click Simulate and run the configured analyses.
  3. Add probes to the key nodes to view the expected behavior.

Notes

  • Increase R or C to lower the cutoff frequency.
