Abstract
This paper presents the results of modeling of several digital filtering algorithms of the ADC output codes for suppressing periodic and impulse noise signals and normal noise. The algorithms were tested in LabVIEW. It was shown that they provided real-time suppression of normal and impulse noise to a level from −57 to −63 dB.
