The questions of elimination additive low-frequency noise affecting to electrocardio signal such baseline drift and powerline interference are discussed. This paper describes novel methods for separation interference form electrocardio signal based on filtering the sequence of ECS samples taken at the TP segment in each cycle of heart rate. It is shown that in this case all of spectral components of electrocardio signal are unchanged and when converting the sample TP segments in the group of samples is possible to extend the frequency band of baseline drift which is eliminated.
