摘要
FIELD: information technology.;SUBSTANCE: digital filtering method enables to pick up a signal in conditions with powerful broadband interference and can be realised in a digital filter. The method involves successive transformation of the filtered signal such that in each filtration step, fourth-order transformation is carried out, having transformation members only during even steps for signal sampled values. As a result of such signal transformation, the number of operations is reduced and operating speed is increased during filtration. The digital filter has a simple design and can be made using standard components.;EFFECT: higher speed of operation during band-pass filtering.;3 cl, 7 dwg
