FIELD: automation and information technology.
SUBSTANCE: invention relates to automation and information technology and can be used in digital systems for measuring the parameters of various objects. A digital IIR filter with a resampling circuit, made in a homogeneous register environment, contains a clock pulse generation unit, a resampling unit containing an analog-to-digital converter and a frequency expander, a filter type code storage unit, a filter structure code storage unit, a filtering unit, a memory unit.
EFFECT: implementation of a digital IIR filter in a homogeneous environment with a resampling circuit, which ensures the speed of the filtering algorithm at reduced computational costs without changing the initial characteristics of the filter, as well as the flexibility of reading the result of processing the input signal due to its storage in a memory device.
