FIELD: information technology.
SUBSTANCE: system can comprise: first filter unit (12), filtering input signal in initial sub-interval (Tl) in current update interval (T) in accordance with parameters associated with previous update interval, wherein the parameters are scaled to a first scaling coefficient (sk-1) varying towards 0Tl; second filter unit (14), filtering input signal (13) of the second filter based on the output of the first filter unit at the initial interval (Tl) in accordance with parameters associated with the current update interval (T), wherein parameters are scaled to a second scaling coefficient (sk) varying from 0 or a value close to 0 towards a value farther from 0Tl.
EFFECT: methods and systems for filtering an information input signal are considered.
