CIRCUIT ARRANGEMENT AND METHOD FOR REGULATING ADMISSIBLE CIRCUIT DEVIATIONS Russian patent published in 2008 - IPC H03H7/12 

FIELD: radio engineering; adjusting frequency-dependent filters.

SUBSTANCE: proposed regulating device designed to adjust frequency response of filter has time-constant transducer that function to measure state of filter charge and to withdraw measurement results from mentioned time-constant transducer in the form of first voltage; converter used to digitize first voltage and to withdraw second voltage obtained as result of first-voltage conversion by mentioned converter; array of adjusting components; and selector using second voltage for selecting at least one adjusting component out of array of adjusting components; state of circuit charge can be adjusted in proposed device by means of at least one chosen adjusting component; mentioned time-constant transducer of proposed device has in addition change-over controller that functions to control at least one charge switch; closure of the latter switches filter over to state of charge.

EFFECT: reduced admissible differences between measured and desired values of frequency-dependent filter components.
