Savitsky-Golay Filters
written by
Robert DeSerio
This paper describes how to create Savitsky-Golay filters for smoothing and determining derivatives from raw data taken at points equally spaced in time based on a polynomial fitting model. For example, they can be used to evaluate velocity and acceleration from ultrasonic motion sensor data and angular velocity and acceleration from rotary encoder data.
