PURPOSE:To attain the flexible consecution time of elimination object noise without losing the miniaturization and economy by selecting a storage signal this time or a preceding stored output signal in response to the result of recent comparison of digital signals at a prescribed number of times. CONSTITUTION:Recent digital input signals di coming m-times or the like are stored in plural-set (e.g., m) of 1st storage means 100, they are compared by a comparison means 200 and a selection means 400 is controlled in response to the result of comparison. Then when they are all coincident, the storage content of the means 100 is outputted, and if they are dissident, the preceding output stored in the 2nd storage means 300 is outputted. Thus, momentary noise is eliminated without adding a parity bit to the digital signal and the consecutive time of momentary noise being an object of elimination is adjusted easily and flexibly without losing the miniaturization and the economy. |
