FIELD: measuring equipment.
SUBSTANCE: invention relates to means of measuring equipment and can be used as tunable spectrum limiters connected at the input of analogue-to-digital converters for various purposes. Universal programmable ARC filter based on R-2R matrices also includes differential operational amplifiers, resistors and capacitors connected to each other so as to provide tuning of quasi-resonance frequency of filters, frequency of LPF pole and HPF pole frequency, compensation of effect of frequency characteristics of operational amplifiers increases stability and Q factor of active programmable filter.
EFFECT: technical result consists in improvement of the implemented Q-factor stability.
