Course: Design and validate the telemetry system that feeds every decision

Module: Sample fast enough without drowning in data

Estimated duration: 20 minutes

This lesson covers analog low-pass filter design (order, cutoff, phase lag) and digital decimation strategies that preserve signal integrity while keeping file sizes manageable. WHY: aggressive filtering removes noise but also delays phase, which corrupts time-synchronised comparisons (e.g. brake p
