FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used to select given signal spectra, for example, during their analogue-to-digital conversions. Result is provided due to the fact that the second capacitor is connected between the common unit of the series-connected first and second electronic switches and the common power supply bus, between the common unit of the second electronic switch and the first capacitor a second voltage follower is connected, output of which is connected to inverting input of differential operational amplifier through series-connected third and fourth electronic switches, common node of which is connected to common bus of power sources through third capacitor.
EFFECT: high quality factor at smaller ratio of capacitances of frequency-setting capacitors in a discrete-analogue filter.
