Presets
A filter passes some frequencies and blocks others. The cutoff fc = 1/(2πRC) is where the response falls 3 dB; beyond it the magnitude rolls off at 20 dB per decade per order — steeper filters cut harder. Educational tool.

Governing equation
Reading this result: The −3 dB cutoff sits at 1.0 kHz, where the low-pass response begins to roll off. Order 2 sets the steepness at 40 dB/decade — a gentle slope that eases into the stopband with minimal ringing. Raising the order steepens the roll-off while adding phase lag around the cutoff.
