WebA lowpass filter used for that purpose is called an anti-aliasing filter. In a digital signal received from a sensor (e.g., a motion detector), the data might be noisy and jittery or might contain occasional spurious incorrect values. A smoothing lowpass filter can smooth out those inconsistencies.
