An iterative and continuous normalizer for ensuring that the ejector rate of the slave channels in a fungible product sorter are operating at the same rate as a channel selected as the master channel. A distributed trip level value applied to a master channel comparator results in a rate of ejection of non-standard products that are counted to a predetermined count, at which time a master channel counter output is produced. In similar fashion, a slave channel output is produced; however, the comparator in the slave channel operates to an adjusted trip level value, which is the distributed trip level value adjusted by a multiplying factor. This multiplying factor is produced by a multiplier controlled by an up/down counter, in turn controlled up or down by whether the slave channel counter output or master channel counter output arrives first. The multiplier makes the adjusted trip level value higher or lower to change the sensitivity of the slave channel to keep it operating at the same rate as the master channel operation.
