Abstract

A computer is programmed to provide a moving average filter process which designates, 50, an initial filter constant to control the filter response time maintains a moving average signal value finds, 54, a difference between the moving average and each new signal sample amplitude before the new amplitude is included in the moving average updates, 66, the average by adding to it, at a time of each new signal sample, a value calculated by dividing the difference by the initial filter constant and when a sequential plurality of the found difference values manifest an identical polarity, divides, 64, the initial filter constant by an integer factor which thereby reduces the filter response time. When, by contrast, a found difference value manifests a different polarity from an immediately preceding found difference value, the filter constant is multiplied, 68, by an integer factor so as to increase the response time.
