Abstract
A number of consecutive samples in unit distance code (here Gray code) are effectively stacked and supplied to respective sum and threshold devices 20 corresponding to each bit position, to determine the bulk property or “generic result” of the consecutive samples. This filtered output is converted back to binary and analogue if required. The digital filter may be used in any of the above applications to “clean” data.
