ABSTRACT:
A noise detecting circuit for a data processing channel operates on incoming noise pulses and trains of data pulses, each train of which is preceded by a start pulse of a duration substantially greater than the characteristic duration of a noise pulse. The noise detecting circuit generates a noise verification pulse in response to a first incoming pulse after a predetermined interval of time following the receipt of the first incoming pulse, which interval is greater than the characteristic duration of a noise pulse and less than the duration of a start pulse. Consequently, there is time coincidence between the noise verification pulse and the first incoming pulse if the first incoming pulse is a start pulse but there is no time coincidence between the noise verification pulse and the first incoming pulse if the first incoming pulse is a noise pulse. Means are included for detecting such non-coincidence and for generating an inhibit signal to indicate that the first incoming pulse is a noise pulse and to inhibit a data processing channel from processing the next incoming pulse.
