A short follow up to my previous video on RC filter design, demonstrating the phase delay through a multi-stage Sallen-Key low pass filter (Chebyshev response).
An introduction to passive and active low pass filters, filter requirements and design concerns, and the evolution from a simple single-pole RC filter to a multi-stage Sallen-Key topology.
