TRUE MEAN RATE MEASURING SYSTEM

A micro-computer circuit including a read-only memory averages pulse information at a plurality of averaging levels with each averaging level corresponding to a progressively increasing maximum count level and generates a best estimate of the true mean rate of the pulse information wherein the best estimate corresponds to the average of the averaging level of the highest full count. If the pulse information remains stationary the averaging process continues to provide desired system resolution. If however the pulse information is determined to be non-stationary a new best estimate is developed to provide desired system accuracy. An optimum trade-off between system accuracy and resolution is thus achieved.
