〰️ Sallen-Key Active Low-Pass Filter (2D schematic and Bode plot)

2D schematic and scope of a Sallen-Key second-order low-pass filter: change R, C and gain, and watch the Bode plot, pole map, scope trace and step response. Same transfer-function module as the 3D page, cross-checked by an RK4 simulation of the circuit equations.
