FIELD: engineering of informational and transformation equipment when used as primarily intended, and may be used as primarily intended and during realization of functional transformers, angle meters, etc. ^ SUBSTANCE: one-channel infra-low-frequency filter contains multiplexers, subtraction block, division block, phase shifters, block for transformation of inverse tangent, block for generation of correction value, commutator, counting-registering block, block for determining correction value and control block. ^ EFFECT: increased precision of measurements due to introduction of corrections to result of measurement, allowing to exclude ambiguousness of determined phase shift of sinusoidal signals. ^ 1 dwg |
