Abstract: Head impact sensors worn in the mouth are popular because they couple directly to the teeth and provide six-degree-of-freedom head measurements. Mouthpiece signal filters have conventionally used cutoff frequencies lower than recommended practices (Society of… read more here.

Abstract: This paper aims to design variable fractional-delay (VFD) finite-impulse response (FIR) filters with controllable cutoff frequencies. Different with the existing designs, a particular ladder-shaped curve is selected as the desired transfer characteristic of the proposed… read more here.
