Abstract
In the control system disclosed herein, multiple input data streams are processed or filtered to generate multiple output streams by a filter which combines efficient batch processing of a fixed number of older input samples with immediate direct processing of a varying number of current samples thereby to generate multiple output data streams which are based on essentially current input data as well as older input data reaching back for a time interval which varies periodically.
