– Filtered signal is delayed with respect to real time signal.
– MSI 60 filters have constant, frequency independent delay.
– Delay (e.g. 22 samples at 10 ms) is corrected during recording.
– No delay filtered vs. unfiltered in recorded data.
– Correction is (of course) not possible for real time data (display, online, PWM out).
– Use filtered data for recording, use unfiltered data for realtime.

Example: Measurement of wheel speed
– Pulse wheel attached to wheel
– Each passing tooth of pulse wheel triggers Hall sensor
– Calculation of wheel speed with wheel circumference
