Abstract
An averaging circuit for producing average boat speed and average apparent wind speed which in cooperation with average apparent wind direction are utilized to determine the performance characteristics of sailing boats. Instantaneous values of the speed parameters are sampled at a predetermined frequency and a running average of N samples is generated by adding the most recent sample and discarding the oldest sample at periodic intervals. Display of the wind speed is delayed with respect to the display of boat speed to compensate for the effect of the inertia of the boat.
