Effect of Digital Filter Width on Ramp-Up

• 30-90Hz

• 30-90Hz digital filter ramps up within a 1/120th second (half of 1/60th of a second)

• Too slow a ramp-up would require monitoring an input longer before taking a measurement, and slow down the number of measurements per second we could make.
