openrcfilter
Design a filter that removes noise from a sensor signal, in three sessions.
- Session 1: A resistor and a capacitor smooth a noisy signal (Level 1, 60 min)
- Session 2: The RC low-pass in numbers: tau, cutoff, decibels and the Bode plot (Level 2, 75 min)
- Session 3: Digital filters: the exponential moving average, Butterworth and the limits (Level 3, 90 min)
