FIELD: information technologies.
SUBSTANCE: invention relates to specialised computer means and may be used in systems, where hardware implementation of algorithms of digital signal filtration is required. For instance, when zero level is assessed at the background of pulse signals/noise or under conditions of asymmetrical limitation of dynamic range, relative to zero level. Digital filter comprises digital comparator (1), the first and second reversive counters (2, 3).
EFFECT: simplified hardware implementation of digital filter for assessment of slowly changing median of signal.
