Abstract
Abstract Disclosed are a system for and method of analyzing a property of a moving sheet in response to sampled data derived from a plurality of scans of a transducer for the property across the sheet. A composite profile of the plural scans is obtained by averaging the property values for corresponding across the sheet points over several scans. To preserve computer memory, the average values of a plurality of samples within each scan are derived and then stored. The number of sampling points within each scan is determined either on an a priori basis or in response to the ratio over the several scans of the total variance of the process to a predetermined, desired variance of the average of the property determined from the sampled values within each scan. The number of sampling points comprising a single average is selected as an odd number.
