ABSTRACT:
Data processing methods and circuit arrangements are provided whereby out of a succession of data, some or most of which are false due to interference or noise, only those most likely to be true are selected for transmission to following stages of processing. Selection is achieved by comparing, according to a predetermined criterion, successive input data words with a data word already held in a data store and updating the store by discarding the stored data word and replacing it with an input data word whenever an input data word meets the predetermined criterion. A stored data word is utilised in further processing only when a predetermined number of input data words have been compared with the stored data word without updating having occurred. The invention has particular relevance to optical pyrometry systems.
