Vertical dashed line = cutoff frequency | Red line = -3dB point (half power)

What you learned

  • Understand how rolloff rate (dB/oct) affects filter steepness
  • Learn the relationship between poles and rolloff (6dB per pole)
  • Visualize the -3dB point at the cutoff frequency
  • Compare different filter types (LPF, HPF, BPF, Notch)
  • Explore how resonance creates a peak at the cutoff frequency
